Enhanced-Fidelity Ultrafast Geometric Quantum Computation Using Strong Classical Drives
Ye-Hong Chen, Adam Miranowicz, Xi Chen +2
We propose a general approach to implement nonadiabatic geometric single- and two-qubit gates beyond the rotating wave approximation (RWA). This protocol is compatible with most op…
Experimental quantum simulation of superradiant phase transition beyond no-go theorem via antisqueezing
Xi Chen, Ze Wu, Min Jiang +3
Superradiant phase transition (SPT) in thermal equilibrium, as a fundamental concept bridging the statistical physics and electrodynamics, can offer the key resources for quantum i…
Experimental implementation of precisely tailored light-matter interaction via inverse engineering
Ying Yan, Chunyan Shi, Adam Kinos +6
Accurate and efficient quantum control in the presence of constraints and decoherence is a requirement and a challenge in quantum information processing. Shortcuts to adiabaticity,…
Experimental Observation of Equilibrium and Dynamical Quantum Phase Transitions via Out-of-Time-Ordered Correlators
Xinfang Nie, Bo-Bo Wei, Xi Chen +8
The out-of-time-ordered correlators (OTOC) have been established as a fundamental concept for quantifying quantum information scrambling and diagnosing quantum chaotic behavior. Re…
Experimental Cryptographic Verification for Near-Term Quantum Cloud Computing
Xi Chen, Bin Cheng, Zhaokai Li +4
Recently, there are more and more organizations offering quantum-cloud services, where any client can access a quantum computer remotely through the internet. In the near future, t…
Enhanced precision bound of low-temperature quantum thermometry via dynamical control
Victor Mukherjee, Analia Zwick, Arnab Ghosh +2
High-precision low-temperature thermometry is a challenge for experimental quantum physics and quantum sensing. Here we consider a thermometer modelled by a dynamically-controlled…
High-fidelity adiabatic quantum computation using the intrinsic Hamiltonian of a spin system: Application to the experimental factorization of 291311
Zhaokai Li, Nikesh S. Dattani, Xi Chen +6
In previous implementations of adiabatic quantum algorithms using spin systems, the average Hamiltonian method with Trotter's formula was conventionally adopted to generate an effe…
