Dilation of states and processes in operational-probabilistic theories
Giulio Chiribella
This paper provides a concise summary of the framework of operational-probabilistic theories, aimed at emphasizing the interaction between category-theoretic and probabilistic stru…
Replicating the benefits of closed timelike curves without breaking causality
Xiao Yuan, Syed M. Assad, Jayne Thompson +6
In general relativity, closed timelike curves can break causality with remarkable and unsettling consequences. At the classical level, they induce causal paradoxes disturbing enoug…
Limits of optimal control yields achievable with quantum controllers
Re-Bing Wu, Constantin Brif, Matthew R. James +1
In quantum optimal control theory, kinematic bounds are the minimum and maximum values of the control objective achievable for any physically realizable system dynamics. For a give…
Squeezed Optomechanics with Phase-matched Amplification and Dissipation
Xin-You Lü, Ying Wu, J. R. Johansson +3
We investigate the nonlinear interaction between a squeezed cavity mode and a mechanical mode in an optomechanical system (OMS) that allows us to selectively obtain either a radiat…
Universal super-replication of unitary gates
G. Chiribella, Y. Yang, C. Huang
Quantum states obey an asymptotic no-cloning theorem, stating that no deterministic machine can reliably replicate generic sequences of identically prepared pure states. In stark c…
Experimental entanglement-assisted quantum delayed-choice experiment
Tao Xin, Hang Li, Bi-Xue Wang +1
The puzzling properties of quantum mechanics, wave-particle duality, entanglement and superposition, were dissected experimentally at past decades. However, hidden-variable (HV) mo…
Experimental Estimation of Average Fidelity of a Clifford Gate on a 7-qubit Quantum Processor
Dawei Lu, Hang Li, Denis-Alexandre Trottier +8
Quantum gates in experiment are inherently prone to errors that need to be characterized before they can be corrected. Full characterization via quantum process tomography is impra…
Quantum Simulation of Pairing Hamiltonians with Nearest-Neighbor Interacting Qubits
Zhixin Wang, Xiu Gu, Lian-Ao Wu +1
Although a universal quantum computer is still far from reach, the tremendous advances in controllable quantum devices, in particular with solid-state systems, make it possible to…
Experimental Realization of Universal Geometric Quantum Gates with Solid-State Spins
C. Zu, W. -B. Wang, L. He +4
Experimental realization of a universal set of quantum logic gates is the central requirement for implementation of a quantum computer. An all-geometric approach to quantum computa…
Conservation of information and the foundations of quantum mechanics
G. Chiribella, C. M. Scandolo
We review a recent approach to the foundations of quantum mechanics inspired by quantum information theory. The approach is based on a general framework, which allows one to addres…
Optomechanically-Induced Transparency in partiy-time-symmetric microresonators
H. Jing, S. K. Özdemir, Z. Geng +5
Optomechanically-induced transparency (OMIT) and the associated slowing of light provide the basis for storing photons in nanoscale devices. Here we study OMIT in parity-time (PT)-…
Realistic Interpretation of Quantum Mechanics and Encounter-Delayed-Choice Experiment
Gui-Lu Long, Wei Qin, Zhe Yang +1
A realistic interpretation(REIN) of wave function in quantum mechanics is briefly presented in this work. In REIN, the wave function of a microscopic object is just its real existe…
Experimental Quantum Hamiltonian Identification from Measurement Time Traces
Shi-yao Hou, Hang Li, Gui-Lu Long
Identifying Hamiltonian of a quantum system is of vital importance for quantum information processing. In this Letter, we realized and benchmarked a quantum Hamiltonian identificat…

Zhu Cao, Zhen Zhang, Hoi-Kwong Lo +1
Coherent state photon sources are widely used in quantum information processing. In many applications, such as quantum key distribution (QKD), a coherent state is functioned as a m…
Randomness Requirement on CHSH Bell Test in the Multiple Run Scenario
Xiao Yuan, Zhu Cao, Xiongfeng Ma
The Clauser-Horne-Shimony-Holt inequality test is widely used as a mean of invalidating the local deterministic theories and a tool of device independent quantum cryptographic task…
Experimental Test of Quantum Jarzynski Equality with a Trapped Ion System
Shuoming An, Jing-Ning Zhang, Mark Um +6
The past two decades witnessed important developments in the field of non-equilibrium statistical mechanics. Among these developments, the Jarzynski equality, being a milestone fol…
Quasi-quantization: classical statistical theories with an epistemic restriction
Robert W. Spekkens
A significant part of quantum theory can be obtained from a single innovation relative to classical theories, namely, that there is a fundamental restriction on the sorts of statis…
