High-performance cavity-enhanced quantum memory with warm atomic cell
Nature Communications, 2022 Quantum memories usually suffer from a trade-off between efficiency and excess noise. Here, by exploiting the time-reversal approach for improving modes matching, the authors show a warm-atomic-cell-based cavity-enhanced memory with 67% efficiency and ...

Reconstructing Quantum States With Quantum Reservoir Networks [PDF]
IEEE Transactions on Neural Networks and Learning Systems, 2021 Reconstructing quantum states is an important task for various emerging quantum technologies. The process of reconstructing the density matrix of a quantum state is known as quantum state tomography. Conventionally, tomography of arbitrary quantum states is challenging as the paradigm of efficient protocols has remained in applying specific techniques ...

Thermalization of quantum states [PDF]
Journal of Mathematical Physics, 1999 An exact stochastic model for the thermalization of quantum states is proposed. The model has various physically appealing properties. The dynamics are characterized by an underlying Schrödinger evolution, together with a nonlinear term driving the system toward an asymptotic equilibrium state and a stochastic term reflecting fluctuations.

Long-lived and multiplexed atom-photon entanglement interface with feed-forward-controlled readouts
Communications Physics, 2021 The quantum interface to generate entanglement between a flying photonic qubit and a stationary qubit is a key functionality for the quantum internet. The authors demonstrate a multiplexed quantum interface that stores three long-lived spin-wave qubits ...

Local quantum state marking [PDF]
Physical Review A, 2022 We propose the task of local state marking (LSM), where some multipartite quantum states chosen randomly from a known set of states are distributed among spatially separated parties without revealing the identities of the individual states. The collaborative aim of the parties is to correctly mark the identities of states under the restriction that ...
