Noise-tolerant parity learning with one quantum bit
Daniel K. Park, June-Koo K. Rhee, Soonchil Lee
Demonstrating quantum advantage with less powerful but more realistic devices is of great importance in modern quantum information science. Recently, a significant quantum speedup…
Fidelity of Quantum Teleportation through Noisy Channels
Sangchul Oh, Soonchil Lee, Hai-woong Lee
We investigate quantum teleportation through noisy quantum channels by solving analytically and numerically a master equation in the Lindblad form. We calculate the fidelity as a f…
Qubit geometry and conformal mapping
Jae-weon Lee, Chang Ho Kim, Eok Kyun Lee +2
Identifying the Bolch sphere with the Riemann sphere(the extended complex plane), we obtain relations between single qubit unitary operations and Möbius transformations on the exte…
Quantum Shift Register
Jae-weon Lee, Eok Kyun Lee, Jaewan Kim +1
We consider a quantum circuit in which shift and rotation operations on qubits are performed by swap gates and controlled swap gates. These operations can be useful for quantum com…
Storing unitary operators in quantum states
Jaehyun Kim, Yongwook Cheong, Jae-Seung Lee +1
We present a scheme to store unitary operators with self-inverse generators in quantum states and a general circuit to retrieve them with definite success probability. The continuo…
A Practical Method of Constructing Quantum Combinational Logic Circuits
Jae-Seung Lee, Yongwook Chung, Jaehyun Kim +1
We describe a practical method of constructing quantum combinational logic circuits with basic quantum logic gates such as NOT and general -bit Toffoli gates. This method is use…
