Double-Bracket Algorithmic Cooling
Mohammed Alghadeer, Khanh Uyen Giang, Shuxiang Cao +6
Algorithmic cooling shows that it is possible to locally reduce the entropy of a qubit belonging to an isolated ensemble such as nuclear spins in molecules or nitrogen-vacancy cent…
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…
Role of Riemannian geometry in double-bracket quantum imaginary-time evolution
René Zander, Raphael Seidel, Li Xiaoyue +1
Double-bracket quantum imaginary-time evolution (DB-QITE) is a quantum algorithm which coherently implements steps in the Riemannian steepest-descent direction for the energy cost…
