Effect of Space Order on Impulse Buying: Moderated by Self-Construal.

OBJECTIVE: Impulse buying is a recognized phenomenon as consumers have abundant shopping opportunities. We investigate whether orderly space encourages consumers to buy impulsively and whether this relationship is moderated by self-construal. Specifically, we hypothesize that consumers show greater impulse buying intentions when space is orderly than disorderly. We also hypothesize that when interdependent self-construal is primed, the effect of orderly space on consumers' increased impulse buying intentions will be attenuated. BACKGROUND: Our hypotheses are based on the research about emotions that consumers experience while they shop in a retail store. When the store is orderly, consumers experience pleasure. In contrast, disorganized shelves, unsorted merchandise, and messy clothing racks evoke negative emotions. A recent study shows consumers' positive emotional responses to a retail environment result in heightened impulse buying. METHODS: Two experiments were carried out to test the two hypotheses. Experiment 1 employed a 2 (space order: orderly vs. disorderly) between-subjects design. Participants randomly received one of the two store images and were asked to indicate their impulse-buying intentions. Experiment 2 employed a 2 (space order: orderly vs. disorderly) × 2 (self-construal: independent vs. interdependent) between-subjects design. Participants were randomly given one of the two store images and one of the two self-construal priming tasks to measure their impulse buying intentions. RESULTS: As hypothesized, Experiment 1 demonstrated that participants exerted stronger impulse-buying intentions in an orderly space. Experiment 2 also showed that when participants were primed by interdependent self-construal, their impulse buying intentions did not differ, regardless of whether the space was orderly. IMPLICATIONS: Our findings provide insights for offline store managers. To nudge visitors to buy impulsively, managers should organize their spaces orderly. However, the effect of space order on consumers' impulse buying will disappear when consumers' interdependent self-construal is activated. Our findings contribute to the academic research into the factors that lead consumers to buy impulsively.

The Mediating Effect of Psychological Ownership on the Relationship between Value Co-Creation and the In-App Purchasing Intention of Mobile Games Players.

In previous research on in-app purchasing, one of the revenue sources for mobile games focuses on users' unilateral relationships, such as their achievement, loyalty, and perception. However, little has been discussed about the commercial impact of the bilateral relationship. We extend discussions by examining an unprecedented issue, that is, the role of the bilateral relationships between users and mobile game companies in increasing in-app purchasing intention. We borrow from the business literature and psychology to hypothesize that when mobile game users co-create value with a mobile game company, their psychological ownership of the mobile game increases, which in turn increases their in-app purchasing intentions. To test this hypothesis, we conducted a carefully designed study by recruiting eighty-six Chinese game users. Half of the participants were exposed to an imaginary mobile game whose interface allowed them to co-create value with the mobile game company and the other half were exposed to an identical mobile game whose interface did not. We recruited participants from the two online platforms in which Chinese mobile game players gather-Weibo and WeChat Moment. Using SPSS 26, we conducted an independent samples test to test the effect of value co-creation and employed Hayes Model 4 to test whether psychological ownership mediated the relationship between value co-creation and in-app purchasing intention. We found that (1) when participants were allowed to co-create value, their in-app purchasing intentions increased, and (2) the relationship between value co-creation and in-app purchasing intention was mediated by psychological ownership. Our findings provide fresh insights for mobile game designers and marketers.

Quantum fisher information of an optomechanical force sensor driven by a squeezed vacuum field.

We investigate the enhancement in sensitivity when measuring a weak force through the optical response of an optomechanical oscillator driven by squeezed light. In the context of a quantum sensor based on cavity-optomechanics, the sensitivity scaling measured by the quantum Fisher information for a squeezed vacuum state pump is compared to that for a coherent state pump. We show that squeezed state inputs can produce noise levels below the standard quantum limit and even the Heisenberg limit in given regimes. This study shows that new pathways can be opened for enhanced quantum sensing with optomechanical systems conducive to measuring various physical quantities such as gravitational force, acceleration, and acoustics.

A Behavioral Strategy to Nudge Young Adults to Adopt In-Person Counseling: Gamification.

Mental illness has always been an important issue for young adults. Moreover, initiatives resulting from the outbreak of COVID-19 have had an even greater impact on the mental health of young adults. This study sought to examine the effect of gamification on whether young adults adopt in-person counseling. One hundred twenty young adults (42 males and 78 females) with an average age of 29 years participated in our experiment. In the experiment, a 2 (Gamification: no vs. yes) × 2 (Vividness: low vs. high) between-subjects design was employed. In the "yes" gamification condition, participants decided whether or not to read introductory material about in-person counseling, and also whether or not to adopt in-person counseling in the future. The results of the study show that: (1) gamification increased adoption, (2) participants' perception of subjective usability of in-person counseling mediated the effect of gamification to adoption, and (3) vividness of presentation moderated subjective usability. Our study demonstrated that gamification nudges young adults to adopt in-person counseling while subjective usability mediates the relationship, and vividness moderates the relationship between gamification and subjective usability. Our findings provide counselors fresh insights into motivating people to access counseling services.

Photonic hybrid state entanglement swapping using cat state superpositions.

We propose the use of hybrid entanglement in an entanglement swapping protocol, as means of distributing a Bell state with high fidelity to two parties. The hybrid entanglement used in this work is described as a discrete variable (Fock state) and a continuous variable (cat state super- position) entangled state. We model equal and unequal levels of photonic loss between the two propagating continuous variable modes, before detecting these states via a projective vacuum-one-photon measurement, and the other mode via balanced homodyne detection. We investigate homodyne measurement imperfections, and the associated success probability of the measurement schemes chosen in this protocol. We show that our entanglement swapping scheme is resilient to low levels of photonic losses, as well as low levels of averaged unequal losses between the two propagating modes, and show an improvement in this loss resilience over other hybrid entanglement schemes using coherent state superpositions as the propagating modes. Finally, we conclude that our protocol is suitable for potential quantum networking applications which require two nodes to share entanglement separated over a distance of 5 -- 10 km , when used with a suitable entanglement purification scheme.

Logical measurement-based quantum computation in circuit-QED.

We propose a new scheme of measurement-based quantum computation (MBQC) using an error-correcting code against photon-loss in circuit quantum electrodynamics. We describe a specific protocol of logical single-qubit gates given by sequential cavity measurements for logical MBQC and a generalised Schrödinger cat state is used for a continuous-variable (CV) logical qubit captured in a microwave cavity. To apply an error-correcting scheme on the logical qubit, we utilise a d-dimensional quantum system called a qudit. It is assumed that a three CV-qudit entangled state is initially prepared in three jointed cavities and the microwave qudit states are individually controlled, operated, and measured through a readout resonator coupled with an ancillary superconducting qubit. We then examine a practical approach of how to create the CV-qudit cluster state via a cross-Kerr interaction induced by intermediary superconducting qubits between neighbouring cavities under the Jaynes-Cummings Hamiltonian. This approach could be scalable for building 2D logical cluster states and therefore will pave a new pathway of logical MBQC in superconducting circuits toward fault-tolerant quantum computing.

Hybrid quantum linear equation algorithm and its experimental test on IBM Quantum Experience.

We propose a hybrid quantum algorithm based on the Harrow-Hassidim-Lloyd (HHL) algorithm for solving a system of linear equations. In this paper, we show that our hybrid algorithm can reduce a circuit depth from the original HHL algorithm by means of a classical information feed-forward after the quantum phase estimation algorithm, and the results of the hybrid algorithm are identical to those of the HHL algorithm. In addition, it is experimentally examined with four qubits in the IBM Quantum Experience setups, and the experimental results of our algorithm show higher accurate performance on specific systems of linear equations than that of the HHL algorithm.

Efficient scheme for hybrid teleportation via entangled coherent states in circuit quantum electrodynamics.

We propose a deterministic scheme for teleporting an unknown qubit state through continuous-variable entangled states in superconducting circuits. The qubit is a superconducting two-level system and the bipartite quantum channel is a microwave photonic entangled coherent state between two cavities. A Bell-type measurement performed on the hybrid state of solid and photonic states transfers a discrete-variable unknown electronic state to a continuous-variable photonic cat state in a cavity mode. In order to facilitate the implementation of such complex protocols we propose a design for reducing the self-Kerr nonlinearity in the cavity. The teleporation scheme enables quantum information processing operations with circuit-QED based on entangled coherent states. These include state verification and single-qubit operations with entangled coherent states. These are shown to be experimentally feasible with the state of the art superconducting circuits.

Efficient noiseless linear amplification for light fields with larger amplitudes.

We suggest and investigate a scheme for non-deterministic noiseless linear amplification of coherent states using successive photon addition, (â(†))(2), where â(†) is the photon creation operator. We compare it with a previous proposal using the photon addition-then-subtraction, ââ(†), where â is the photon annihilation operator, that works as an appropriate amplifier only for weak light fields. We show that when the amplitude of a coherent state is |α| ≳ 0.91, the (â(†))(2) operation serves as a more efficient amplifier compared to the ââ(†) operation in terms of equivalent input noise. Using ââ(†) and (â(†))(2) as basic building blocks, we compare combinatorial amplifications of coherent states using (ââ(†))(2), â(†4), ââ(†)â(†2), and â(†2)ââ(†), and show that (ââ(†))(2), â(†2)ââ(†), and â(†4) exhibit strongest noiseless properties for |α| ≲ 0.51, 0.51 ≲ |α| ≲ 1.05, and |α| ≳ 1.05, respectively. We further show that the (â(†))(2) operation can be useful for amplifying superpositions of the coherent states. In contrast to previous studies, our work provides efficient schemes to implement a noiseless amplifier for light fields with medium and large amplitudes.

Quantum metrology with entangled coherent states.

We present an improved phase estimation scheme employing entangled coherent states and demonstrate that these states give the smallest variance in the phase parameter in comparison to NOON, "bat," and "optimal" states under perfect and lossy conditions. As these advantages emerge for very modest particle numbers, the optical version of entangled coherent state metrology is achievable with current technology.

Electromagnetically induced transparency with amplification in superconducting circuits.

We show that controlling relative phases of electromagnetic fields driving an atom with a Δ-configuration energy-level structure enables optical susceptibility to be engineered in novel ways. In particular, relative-phase control can yield electromagnetically induced transparency but with the benefit that the transparency window is sandwiched between an absorption and an amplification band rather than between two absorption bands in typical electromagnetically induced transparency. We show that this new phenomenon is achievable for a microwave field interacting with a fluxonium superconducting circuit.
