Demonstrating advantages of dynamic quantum circuits on a hybrid superconducting qubit-cavity processor
Hongbo Wu, Ling Hu, Jiasheng Mai +10
Dynamic quantum circuits (DQCs) provide a hardware-efficient route to quantum computing by reducing physical-qubit overhead and compressing circuit topology through mid-circuit mea…
Quantum-Enhanced Dark Matter Search Using Cat States
Pan Zheng, Yanyan Cai, Bin Xu +12
Quantum metrology has recently emerged as a powerful approach for dark matter (DM) searches, particularly using nonclassical bosonic states in microwave cavities that are sensitive…
Quantum-enhanced metrology with large Fock states
Xiaowei Deng, Sai Li, Zi-Jie Chen +11
Quantum metrology uses non-classical states, such as Fock states with a specific number of photons, to achieve an advantage over classical sensing methods. Typically, quantum metro…
A biased-erasure cavity qubit with hardware-efficient quantum error detection
Jiasheng Mai, Qiyu Liu, Xiaowei Deng +8
Erasure qubits are beneficial for quantum error correction due to their relaxed threshold requirements. While dual-rail erasure qubits have been demonstrated with a strong error hi…
Autonomous quantum error correction beyond break-even and its metrological application
Zhongchu Ni, Ling Hu, Yanyan Cai +8
The ability to extend the lifetime of a logical qubit beyond that of the best physical qubit available within the same system, i.e., the break-even point, is a prerequisite for bui…
Quantum squeezing amplification with a weak Kerr nonlinear oscillator
Yanyan Cai, Xiaowei Deng, Libo Zhang +8
Quantum squeezed states, with reduced quantum noise, have been widely utilized in quantum sensing and quantum error correction applications. However, generating and manipulating th…
