Reachability Constraints in Variational Quantum Circuits: Optimization within Polynomial Group Module
Yun-Tak Oh, Dongsoo Lee, Jungyoul Park +2
This work identifies a necessary condition for any variational quantum approach to reach the exact ground state. Briefly, the norms of the projections of the input and the ground s…
-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 Photovoltaic Cells Driven by Photon Pulses
Sangchul Oh, Jungjun Park, Hyunchul Nha
We investigate the quantum thermodynamics of two quantum systems, a two-level system and a four-level quantum photocell, each driven by photon pulses as a quantum heat engine. We s…
Information Fluctuation Theorem for an Open Quantum Bipartite System
Jung Jun Park, Hyunchul Nha, Sang Wook Kim +1
We study an arbitrary non-equilibrium dynamics of a quantum bipartite system coupled to a reservoir. For its characterization, we present a fluctuation theorem (FT) that explicitly…
Fluctuation Theorem for Arbitrary Quantum Bipartite Systems
Jung Jun Park, Sang Wook Kim, Vlatko Vedral
We present a fluctuation theorem for quantum bipartite systems in which the subsystems exchange information with each other. Our information fluctuation theorem includes correlatio…
Heat engine driven by purely quantum information
Jung Jun Park, Kang-Hwan Kim, Takahiro Sagawa +1
The key question of this paper is whether work can be extracted from a heat engine by using purely quantum mechanical information. If the answer is yes, what is its mathematical fo…
