Experimental investigation of wave-particle duality relations in asymmetric beam interference
npj Quantum Information, 2022 Wave-particle duality relations are fundamental for quantum physics. Previous experimental studies of duality relations mainly focus on the quadratic relation D 2 + V 2 ≤ 1, based on symmetric beam interference, while a linear form of the duality ...

An ultra-high gain single-photon transistor in the microwave regime
Nature Communications, 2022 Successfully controlling an optical signal by a single gate photon would have great applicability for quantum networks and all-optical computing. Here, the authors realise a single-photon transistor in the microwave regime based on superconducting ...

Quantum information transmission [PDF]
Quantum Information Processing, 2012 We present a scheme of quantum information transmission, which transmits the quantum information contained in a single qubit via the quantum correlation shared by two parties (a two-qubit channel), whose quantum discord is non-zero. We demonstrate that the quantum correlation, which may have no entanglement, is sufficient to transmit the information of

Observation of a quantum phase transition in the quantum Rabi model with a single trapped ion
Nature Communications, 2021 Quantum phase transition occurs in many-body systems with abrupt changes in the ground state around zero temperature. Here the authors report signatures of quantum phase transition in single trapped ion that can be described using quantum Rabi model.

Gaussian quantum information [PDF]
Reviews of Modern Physics, 2012 The science of quantum information has arisen over the last two decades centered on the manipulation of individual quanta of information, known as quantum bits or qubits. Quantum computers, quantum cryptography and quantum teleportation are among the most celebrated ideas that have emerged from this new field.

Persistence of quantum information [PDF]
Physics Letters A, 2007 There is an increasing interest in the role of macroscopic environments to our understanding of the basics of quantum theory. The knowledge of the implications of the quantum theory to other theories, especially to the statistical mechanics and the domain of validity has captivated scientists from the beginning of quantum description. In such a context,

Quantum-enhanced radiometry via approximate quantum error correction
Nature Communications, 2022 Exotic quantum states can be advantageous for sensing, but are very fragile, so that some form of quantum error correction is needed. Here, the authors show how approximate QEC helps overcoming decoherence due to noise when measuring the excitation ...
