Quantifying Nonstabilizerness of Quantum Codes by Removing the Inert Background
Yuan Liu, Ke-Mi Xu
Nonstabilizerness (magic) is the quantum resource that, together with stabilizer operations, makes universal quantum computation possible. However, quantifying nonstabilizerness is…
Approximate Virtual Quantum Recovery
Yuan Liu, Linhan Lin, Ke-Mi Xu
The recovery of quantum information after subsystem loss is a central challenge in quantum information processing. However, some states remain beyond the reach of any recovery stra…
Quantifying Nonstabilizerness of Codeword-Stabilized Codes
Yuan Liu, Ke-Mi Xu
Universal quantum computation requires non-Clifford gates, which stabilizer codes can provide transversally only up to a finite level of the Clifford hierarchy. Non-stabilizer code…
Spatially variant arbitrary polarization shaping for optical skyrmions generation
Yu-Hao Lei, Zi-Ting Liu, Jun-Quan Guo +6
Polarization is fundamental degree of freedom of light, crucial for applications from imaging to quantum optics. Although numerous methods can spatially manipulate the polarization…
Precision Interferometry with Collectively Enhanced Atomic Mirror
Yuan Liu, Ke-Mi Xu, Hong-Bo Sun +1
Quantum metrology exploits quantum resources to enhance measurement precision beyond the classical limit. Conventional protocols normally rely on the preparation of delicate quantu…
