Quantum algorithms without initializing the auxiliary qubits
Dong Pyo Chi, Jeong San Kim, Soojoon Lee
In this Letter, we construct the quantum algorithms for the Simon problem and the period-finding problem, which do not require initializing the auxiliary qubits involved in the pro…

Completely-Positive Non-Markovian Decoherence
Jinhyoung Lee, Inbo Kim, Helen McAneney +2
We propose an effective Hamiltonian approach to investigate decoherence of a quantum system in a non-Markovian reservoir, naturally imposing the complete positivity on the reduced…
