Application and quantum properties of superpositions of oppositely squeezed states

Hiroo Azuma, William J. Munro, Kae Nemoto

We show that superpositions of oppositely squeezed states -- non-Gaussian Schr{ö}dinger-cat-like states -- exhibit enhanced nonclassical features and provide an entanglement advan…

Adaptive Resource and Memory Control for Stability in Quantum Entanglement Distribution

Nicolò Lo Piparo, William J. Munro, Kae Nemoto

We investigate congestion-aware control of quantum repeater nodes operating under stochastic traffic and finite memory coherence. Entanglement generation is modeled as a probabilis…

Use of Faulty States in Cat-Code Error Correction

Michael Hanks, Soovin Lee, Nicolo Lo Piparo +4

Bosonic codes have seen a resurgence in interest for applications as varied as fault tolerant quantum architectures, quantum enhanced sensing, and entanglement distribution. Cat co…

Genuine Tripartite Strong Coupling in a Superconducting-Spin Hybrid Quantum System

Yingqiu Mao, Han-Yu Ren, Zi-Yi Liu +12

We demonstrate genuine tripartite strong coupling in a solid-state hybrid quantum system comprising a superconducting transmon qubit, a fixed-frequency coplanar-waveguide resonator…

Loophole-free Bell-inequality violation between atomic states in cavity-QED systems mediated by hybrid atom-light entanglement

Pei-Zhe Li, Soumyakanti Bose, Hyunseok Jeong +3

We present a feasible and scalable approach to testing Bell nonlocality and implementing device-independent quantum key distribution (DI-QKD) between distant atomic states in cavit…

Integrated Generation and Purification of Entangled Coherent States for Non-Gaussian Teleportation

Ananga Mohan Datta, William J. Munro, Nicolo Lo Piparo +1

Entangled coherent states (ECS) provide a powerful non-Gaussian resource for continuous-variable quantum communication, but their generation in scalable architectures remains chall…
