Direct Detection of Quantum Superposition at a Distance

Abstract

Employing an XOR game, we verify quantum superposition with local measurements only, consisting of photon-counting and coincidence detection and using a second, indistinguishable photon as a shared resource, without the need to re-interfere the superposition.

Direct and efficient detection of quantum superposition

Daniel Kun, Teodor Strömberg, Michele Spagnolo +3 more

One of the most striking quantum phenomena is superposition, where one particle simultaneously inhabits different states. Most methods to verify coherent superposition are indirect, in that they require the distinct states to be recombined. Here, we adapt an game, in which a “test” photon is placed in a superposition of two orthogonal spatial modes, and each mode is sent to separated parties who perform local measurements on their modes without reinterfering the original modes. We show that by using a second identical “measurement” photon the parties are nonetheless able to verify if the test photon was placed in coherent superposition of the two spatial modes. We then turn this game into a resource-efficient verification scheme, obtaining a confidence that the particle is superposed which approaches unity exponentially fast. We demonstrate our scheme using a single photon, obtaining a 99% confidence that the particle is superposed with only 37 copies. Our work shows the utility of games to verify quantum resources, allowing us to efficiently detect quantum superposition without reinterfering the superposed modes.

Visibility-dependent resource scaling analysis for verifying single-particle quantum superposition via XOR games

Ting-Hsun Chien, Chieh-Yu Yao, Chun-Ming Chiang

The verification of single-particle quantum superposition states conventionally relies on the physical recombination of distinct spatial paths within an interferometer. However, this approach is highly susceptible to phase drifts and environmental noise in long-distance distributed quantum systems. To explore the feasibility of quantum verification without path recombination, this study establishes a numerical analysis model for single-particle quantum superposition based on the XOR-game framework. By introducing an ancilla photon indistinguishable from the test photon, the system analyzes the quantum verification capability through statistical correlations derived from local measurements and two-photon interference. Using the interference visibility V as the core parameter, we systematically investigate the minimum number of valid detection events required to achieve a 99% verification confidence level under different interference-quality conditions. The verification significance is evaluated using a one-sided binomial test against the classical local hidden variable (LHV) bound, with an expected-count criterion adopted to provide a deterministic resource-scaling baseline. Our numerical results show that under the ideal condition ( V =1.00), approximately 25 valid detection events are required to reach the 99% confidence threshold, whereas approximately 89 valid detection events are required at V =0.50. As the visibility decreases further, the required statistical resources increase rapidly. Quantitative fitting of the numerical confidence boundary shows that a power-law model provides a substantially better description than an exponential model, with the fitted scaling behavior close to the analytically predicted inverse-square relation N ∝ V −2 . The proposed resource analysis framework provides a quantitative baseline for evaluating the operational viability of task-based verification protocols in distributed photonic quantum architectures.

Understanding of coincidence detection in Franson-type nonlocal correlations for second-order quantum superposition

Byoung Seung HAM

Coincidence detection is a key technique used in nonlocal quantum-correlation measurements to test Bell inequality violation between remotely separated local detectors. With individual uniform intensity of local measurements, the nonlocal correlation fringe is a mysterious quantum feature that cannot be achieved classically. Here, the coincidence detection is coherently investigated to understand the fundamental physics of the nonlocal correlation fringe via second-order quantum superposition between selected nonlocal measurement events. Because of the coherence feature of paired photons, the coincidence technique modifies the measurement events for the rule of thumb of indistinguishability between selected measurement bases of paired photons. This indistinguishability is quantum superposition between nonlocally detected events resulting from a selected time slot of coincidence, where coherence between individually measured photons is an absolute condition.

Second-order interference of two independent and tunable single-mode continuous-wave lasers

Jianbin Liu, Dong Wei, Hui Chen +5 more

The second-order temporal interference of two independent single-mode continuous-wave lasers is discussed by employing two-photon interference in Feynman's path integral theory. It is concluded that whether the second-order temporal interference pattern can or cannot be retrieved via two-photon coincidence counting rate is dependent on the resolution time of the detection system and the frequency difference between these two lasers. Two identical and tunable single-mode continuous-wave diode lasers are employed to verify the predictions. These studies are helpful to understand the physics of two-photon interference with photons of different spectra.
