Signature of Scramblon Effective Field Theory in Random Spin Models
Zeyu Liu, Pengfei Zhang
Information scrambling refers to the propagation of information throughout a quantum system. Its study not only contributes to our understanding of thermalization but also has wide…
Full Counting Statistics across the Entanglement Phase Transition of Non-Hermitian Hamiltonians with Charge Conservations
Tian-Gang Zhou, Yi-Neng Zhou, Pengfei Zhang
Performing quantum measurements produces not only the expectation value of a physical observable but also the probability distribution of all possible outcomes . The…
Dynamical Transition of Operator Size Growth in Quantum Systems Embedded in an Environment
Pengfei Zhang, Zhenhua Yu
In closed generic many-body systems, unitary evolution disperses local quantum information into highly non-local objects, resulting in thermalization. Such a process is called info…
Synthesizing five-body interaction in a superconducting quantum circuit
Ke Zhang, Hekang Li, Pengfei Zhang +10
Synthesizing many-body interaction Hamiltonian is a central task in quantum simulation. However, it is challenging to synthesize interactions including more than two spins. Borrowi…
Stark many-body localization on a superconducting quantum processor
Qiujiang Guo, Chen Cheng, Hekang Li +9
Quantum emulators, owing to their large degree of tunability and control, allow the observation of fine aspects of closed quantum many-body systems, as either the regime where ther…
Observation of Two-Vertex Four-Dimensional Spin Foam Amplitudes with a 10-qubit Superconducting Quantum Processor
Pengfei Zhang, Zichang Huang, Chao Song +8
Quantum computers are an increasingly hopeful means for understanding large quantum many-body systems bearing high computational complexity. Such systems exhibit complex evolutions…
Probing the dynamical phase transition with a superconducting quantum simulator
Kai Xu, Zheng-Hang Sun, Wuxin Liu +9
Non-equilibrium quantum many-body systems, which are difficult to study via classical computation, have attracted wide interest. Quantum simulation can provide insights into these…
Dephasing-insensitive quantum information storage and processing with superconducting qubits
Qiujiang Guo, Shi-Biao Zheng, Jianwen Wang +11
A central task towards building a practical quantum computer is to protect individual qubits from decoherence while retaining the ability to perform high-fidelity entangling gates…
Continuous-variable geometric phase and its manipulation for quantum computation in a superconducting circuit
Chao Song, Shi-Biao Zheng, Pengfei Zhang +10
Geometric phase, associated with holonomy transformation in quantum state space, is an important quantum-mechanical effect. Besides fundamental interest, this effect has practical…
Emulating many-body localization with a superconducting quantum processor
Kai Xu, Jin-Jun Chen, Yu Zeng +12
The law of statistical physics dictates that generic closed quantum many-body systems initialized in nonequilibrium will thermalize under their own dynamics. However, the emergence…
10-qubit entanglement and parallel logic operations with a superconducting circuit
Chao Song, Kai Xu, Wuxin Liu +16
Here we report on the production and tomography of genuinely entangled Greenberger-Horne-Zeilinger states with up to 10 qubits connecting to a bus resonator in a superconducting ci…
