Gauge-Symmetry Protection Using Single-Body Terms
Jad C. Halimeh, Haifeng Lang, Julius Mildenberger +2
Quantum-simulator hardware promises new insights into problems from particle and nuclear physics. A major challenge is to reproduce gauge invariance, as violations of this quintess…
A Universal Quantum Computing Virtual Machine
Qian-Tan Hong, Zi-Yong Ge, Wen Wang +8
A medium-scale quantum computer with full universal quantum computing capability is necessary for various practical aims and testing applications. Here we report a 34-qubit quantum…
Dynamical quantum phase transition for mixed states in open systems
Haifeng Lang, Yixin Chen, Qiantan Hong +1
Based on a kinematic approach in defining a geometric phase for a density matrix, we define the generalized Loschmidt overlap amplitude (GLOA) for an open system for arbitrary quan…
Diagonal entropy in many-body systems: Volume effect and quantum phase transitions
Zhengan Wang, Zheng-Hang Sun, Yu Zeng +4
We investigate the diagonal entropy(DE) of the ground state for quantum many-body systems, including the XY model and the Ising model with next nearest neighbour interactions. We f…
