Efficient multimode Wigner tomography
Kevin He, Ming Yuan, Yat Wong +4
Advancements in quantum system lifetimes and control have enabled the creation of increasingly complex quantum states, such as those on multiple bosonic cavity modes. When characte…
Optimized protocols for duplex quantum transduction
Zhaoyou Wang, Mengzhen Zhang, Yat Wong +2
Quantum transducers convert quantum signals through hybrid interfaces of physical platforms in quantum networks. Modeled as quantum communication channels, performance of unidirect…
Entanglement trimming in stabilizer formalism
Changchun Zhong, Yat Wong, Liang Jiang
Suppose in a quantum network, there are qubits hold by Alice, Bob and Charlie, denoted by systems , and , respectively. We require the qubits to be described by a sta…
Path-Independent Quantum Gates with Noisy Ancilla
Wen-Long Ma, Mengzhen Zhang, Yat Wong +5
Ancilla systems are often indispensable to universal control of a nearly isolated quantum system. However, ancilla systems are typically more vulnerable to environmental noise, whi…
