Manipulating heterogeneous quantum resources over a network
Ray Ganardi, Jeongrak Son, Jakub Czartowski +2
Quantum information processing relies on a variety of resources, including entanglement, coherence, non-Gaussianity, and magic. In realistic settings, protocols run on networks of…
Gaussian time-translation covariant operations: structure, implementation, and thermodynamics
Xueyuan Hu, Lea Lautenbacher, Giovanni Spaventa +3
Time-translation symmetry strongly constrains physical dynamics, yet systematic characterization for continuous-variable systems lags behind its discrete-variable counterpart. We c…
Thermal operations from informational equilibrium
Seok Hyung Lie, Jeongrak Son, Paul Boes +2
Thermal operations are quantum channels that have taken a prominent role in deriving fundamental thermodynamic limitations in quantum systems. We show that these channels are uniqu…
Grover's algorithm is an approximation of imaginary-time evolution
Yudai Suzuki, Marek Gluza, Jeongrak Son +3
We reveal the power of Grover's algorithm from thermodynamic and geometric perspectives by showing that it is a product formula approximation of imaginary-time evolution (ITE), a R…
Double-bracket algorithm for quantum signal processing without post-selection
Yudai Suzuki, Bi Hong Tiang, Jeongrak Son +3
Quantum signal processing (QSP), a framework for implementing matrix-valued polynomials, is a fundamental primitive in various quantum algorithms. Despite its versatility, a potent…
Generalized Numerical Framework for Improved Finite-Sized Key Rates with Rényi Entropy
Rebecca R. B. Chung, Nelly H. Y. Ng, Yu Cai
Quantum key distribution requires tight and reliable bounds on the secret key rate to ensure robust security. This is particularly so for the regime of finite block sizes, where th…
Catalytic channels are the only noise-robust catalytic processes
Jeongrak Son, Ray Ganardi, Shintaro Minagawa +3
Catalysis refers to the possibility of enabling otherwise inaccessible quantum state transitions by supplying an auxiliary system, provided that the auxiliary is returned to its in…
Double-bracket quantum algorithms for quantum imaginary-time evolution
Marek Gluza, Jeongrak Son, Bi Hong Tiang +5
Efficiently preparing approximate ground-states of large, strongly correlated systems on quantum hardware is challenging and yet nature is innately adept at this. This has motivate…
Double-bracket quantum algorithms for high-fidelity ground state preparation
Matteo Robbiati, Edoardo Pedicillo, Andrea Pasquale +13
Ground state preparation is a central application for quantum computers but remains challenging in practice. In this work, we quantitatively investigate the performance and gate co…
Second Law of Entanglement Manipulation with Entanglement Battery
Ray Ganardi, Tulja Varun Kondra, Nelly H. Y. Ng +1
A central question since the beginning of quantum information science is how two distant parties can convert one entangled state into another. It has been conjectured that such con…
Entanglement generation from athermality
A. de Oliveira Junior, Jeongrak Son, Jakub Czartowski +1
We investigate the thermodynamic constraints on the pivotal task of entanglement generation using out-of-equilibrium states through a model-independent framework with minimal assum…
Quantum Dynamic Programming
Jeongrak Son, Marek Gluza, Ryuji Takagi +1
We introduce a quantum extension of dynamic programming, a fundamental computational method that efficiently solves recursive problems using memory. Our innovation lies in showing…
