-depth-optimized Quantum Search with Quantum Data-access Machine
Jung Jun Park, Kyunghyun Baek, M. S. Kim +3
Quantum search algorithms offer a remarkable advantage of quadratic reduction in query complexity using quantum superposition principle. However, how an actual architecture may acc…
Polynomial T-depth Quantum Solvability of Noisy Binary Linear Problem: From Quantum-Sample Preparation to Main Computation
Wooyeong Song, Youngrong Lim, Kabgyun Jeong +4
The noisy binary linear problem (NBLP) is known as a computationally hard problem, and therefore, it offers primitives for post-quantum cryptography. An efficient quantum NBLP algo…
Quantum solvability of noisy linear problems by divide-and-conquer strategy
Wooyeong Song, Youngrong Lim, Kabgyun Jeong +5
Noisy linear problems have been studied in various science and engineering disciplines. A class of "hard" noisy linear problems can be formulated as follows: Given a matrix $\hat{A…
Coarsening Measurement References and the Quantum-to-Classical Transition
Hyunseok Jeong, Youngrong Lim, M. S. Kim
We investigate the role of inefficiency in quantum measurements in the quantum-to-classical transition, and consistently observe the quantum-to-classical transition by coarsening t…
Qubit Mediated Time Robust Entangling of Oscillators in Thermal Environments
Tommaso Tufarelli, M. S. Kim, Sougato Bose
We consider two separated oscillators initially in equilibrium and continuously interacting with thermal environments, and propose a way to entangle them using a mediating qubit. A…
Suitability of the approximate superposition of squeezed coherent states for various quantum protocols
Petr Marek, M. S. Kim
A state in a d-dimensional Hilbert space can be simulated by a state defined in a different dimension with high fidelity. We assess how faithfully such the approximated state can p…
