Approaching Heisenberg-scalable thermometry with built-in robustness against noise
Da-Jian Zhang, D. M. Tong
It is a major goal in quantum thermometry to reach a scaling of thermometric precision known as Heisenberg scaling but is still in its infancy to date. The main obstacle is t…
General approach to find steady-state manifolds in Markovian and non-Markovian systems
Da-Jian Zhang, Xiao-Dong Yu, Hua-Lin Huang +1
Steady-state manifolds of open quantum systems, such as decoherence-free subspaces and noiseless subsystems, are of great practical importance to the end of quantum information pro…
Universal freezing of asymmetry
Da-Jian Zhang, Xiao-Dong Yu, Hua-Lin Huang +1
Asymmetry of quantum states is a useful resource in applications such as quantum metrology, quantum communication, and reference frame alignment. However, asymmetry of a state tend…
Theorem on the existence of a nonzero energy gap in adiabatic quantum computation
Da-Jian Zhang, Xiao-Dong Yu, D. M. Tong
Adiabatic quantum computation, based on the adiabatic theorem, is a promising alternative to conventional quantum computation. The validity of an adiabatic algorithm depends on the…
