Anonymous quantum sensing robust against state preparation errors
Hiroto Kasai, Seiichiro Tani, Yasuhiro Tokura +1
Networked quantum sensors have several applications such as the mapping of magnetic fields. When the magnetic fields are biomagnetic ones, i.e., they contain some private informati…
Thermal conductance at the superradiant phase transition in the quantum Rabi model
Tsuyoshi Yamamoto, Yasuhiro Tokura
The quantum Rabi model exhibits a superradiant phase transition when the coupling becomes strong, even though it involves only two components: a two-level atom and a single bosonic…
A New Scaling Function for QAOA Tensor Network Simulations
Goro Miki, Yasuhiro Tokura
With the rapid development of quantum computers in recent years, the importance of performance evaluation in quantum algorithms has been increasing. One method that has gained atte…
Energy exchange and fluctuations between a dissipative qubit and a monitor under continuous measurement and feedback
Tsuyoshi Yamamoto, Yasuhiro Tokura
Continuous quantum measurement and feedback induce energy exchange between a dissipative qubit and a monitor even in the steady state, as a measurement backaction. Using the Lindbl…
