Relaxation in quantum dots due to evanescent-wave Johnson noise from a metallic backgate
Amrit Poudel, Luke Langsjoen, Maxim Vavilov +1
We present our study of decoherence in charge (spin) qubits due to evanescent-wave Johnson noise (EWJN) in a laterally coupled double quantum dot (single quantum dot). The high den…
Qubit relaxation from evanescent-wave Johnson noise
Luke S. Langsjoen, Amrit Poudel, Maxim G. Vavilov +1
In many quantum computer architectures, the qubits are in close proximity to metallic device elements. Metals have a high density of photon modes, and the fields spill out of the b…
Quantum efficiency of a microwave photon detector based on a current-biased Josephson junction
Amrit Poudel, Robert McDermott, Maxim G. Vavilov
We analyze the quantum efficiency of a microwave photon detector based on a current-biased Josephson junction. We consider the Jaynes-Cummings Hamiltonian to describe coupling betw…
