Abstract The classical properties of thermal light fields were instrumental in shaping our early understanding light. Before the invention laser, was used to investigate wave-particle duality subsequent formulation quantum theory electromagnetic radiation later confirmed nature fields. Here, we fragment a pseudothermal field into its multiparticle constituents demonstrate that it can host multiphoton dynamics mediated by either or coherence. This is shown forty-particle system through process scattering twisted paths endowed with orbital angular momentum. platform enables accurate projections scattered isolated subsystems governed dynamics. Interestingly, exhibiting coherence produce interference patterns previously attributed entangled optical systems. As such, work unveils novel mechanisms isolate systems from possibility opens new paradigms physics enormous implications for development robust technologies.

Abstract High-dimensional quantum states are known to offer advantages over their two-dimensional qubit counterparts, but preparation and manipulation has been bulky cumbersome. Now, state control demonstrated on-chip with a ~1 μm 2 footprint nm-scale features, producing up eight-dimensional ushering in new route large information encoding on small footprint.

Abstract A theoretical scheme to enhance the sensitivity of a quantum fiber‐optical gyroscope (QFOG) via non‐Gaussian‐state probe based on quadrature measurements optical field is proposed. The utilizes product state comprising photon‐added coherent (PACS) with photon excitations and (CS). QFOG studied it found that can be significantly enhanced through increasing in PACS probe. influence loss performance investigated demonstrated exhibits robust resistance loss. Furthermore, using against two Gaussian‐state probes: CS squeezed (SS) compared indicated offers significant advantage terms sensitivity, regardless loss, under constraint condition same total number input photons. Particularly, three orders magnitude higher than probes for certain values measured parameter. capabilities non‐Gaussian enhancing resisting have wide‐ranging impact future high‐performance QFOGs.

0Revealing nonclassicality of multiphoton optical beams via artificial neural networks

The identification of nonclassical features multiphoton quantum states represents a crucial task in the development many photonic technologies. Under realistic experimental conditions, state gets affected by its interaction with several nonideal optoelectronic devices, including those used to guide, detect, or characterize it. result such noisy is that original get considerably reduced are completely absent detected, final state. In this work, self-learning artificial neural networks exploited experimentally show nonclassicality can be assessed and fully characterized, even cases which concealed measuring devices. Our work paves way toward artificial-intelligence-assisted experimental-setup characterization, as well identification. Published American Physical Society 2024

The symmetric orbital angular momentum (OAM) entanglement in the subspace of { ± ℓ} has been extensively exploited quantum information science. Here we investigate instead Bell inequalities for two-dimensional spanned by asymmetric OAM modes ℓ 1 and 2 , usually corresponding to property nonmaximal entanglement. We demonstrate, both theoretically experimentally, optimal violation a suitable Clauser-Horne-Shimony-Holt inequality modes, thus manifesting states space.

0Quantum Teleportation and EntanglementBased Quantum Blind Signature Protocol for Quantum Secure Communication in Security Service Bases
Опубликована: Ноя. 23, 2023
Quantum teleportation and entanglement-based quantum blind signature protocol were promising new technologies for secure communication between security service bases. They against a variety of attacks, including eavesdropping, signatory disavowal, verifier denial, forgery. The worked by using entanglement to create shared secret state the This was then used generate each message sent verified receiving base state. Compared classical schemes, main advantages its information-theoretic reduced complexity noise. However, this also faced some challenges, such as preparing storing entangled states, performing operations measurements, ensuring trustworthiness third party. Despite these technology like military It had potential revolutionize way that bases communicated with other, making it possible send messages without revealing content or identity messages.
