Low-cost Fredkin gate with auxiliary space
Wen-Qiang Liu, Hai-Rui Wei, Leong-Chuan Kwek
Effective quantum information processing is tantamount in part to the minimization the quantum resources needed by quantum logic gates. Here, we propose an optimization of an n-con…
Efficient Fusion of Photonic W-states with Nonunitary Partial-swap Gates
Hai-Rui Wei, Wen-Qiang Liu, Leong-Chuan Kwek
We introduce a nonunitary partial-swap gate for fusing arbitrary small-sized photonic W-states into a large-scale entangled network of W-state efficiently without ancillary photons…
Persistent Current of SU(N) Fermions
Wayne J. Chetcuti, Tobias Haug, Leong-Chuan Kwek +1
We study the persistent current in a system of SU() fermions with repulsive interaction confined in a ring-shaped potential and pierced by an effective magnetic flux. By applyin…
Optimal Probes for Global Quantum Thermometry
Wai-Keong Mok, Kishor Bharti, Leong-Chuan Kwek +1
Quantum thermodynamics has emerged as a separate sub-discipline, revising the concepts and laws of thermodynamics, at the quantum scale. In particular, there has been a disruptive…
Fully-programmable universal quantum simulator with a one-dimensional quantum processor
V. M. Bastidas, T. Haug, C. Gravel +3
Current quantum devices execute specific tasks that are hard for classical computers and have the potential to solve problems such as quantum simulation of material science and che…
Roadmap on Atomtronics: State of the art and perspective
L. Amico, M. Boshier, G. Birkl +56
Atomtronics deals with matter-wave circuits of ultra-cold atoms manipulated through magnetic or laser-generated guides with different shapes and intensities. In this way, new types…
