Looks like it was cloned. 7 clones should only have a fidelity of O(1/7) or so? Maybe not so Quantum after all....

How to use quantum computers for biomolecular free energies Free energy calculations are at the heart of physics-based analyses of biochemical processes. They allow us to quantify molecular recognition mechanisms, which determine a wide range of biological phe...

If quantum computers are to deliver benefit to biochemistry, they are not going to work in isolation. With FreeQuantum we provide, implement and demonstrate a computational pipeline for computing free energies of biomolecular systems. It is quantum-ready! arxiv.org/abs/2506.20587

Phase estimation with partially randomized time evolution Quantum phase estimation combined with Hamiltonian simulation is the most promising algorithmic framework to computing ground state energies on quantum computers. Its main computational overhead deriv...

I love catching up on my “to read” list of papers on planes.  And today found time to read some recent work on randomized phase estimation arxiv.org/abs/2503.05647 from Gunther et al

The second morning session at #QCTiP2025 featured quantum phase estimation, Hamiltonian simulation, shortest vector problems, verified quantum computing and gates, and entanglement theory by Laura Clinton, Jakob Günther, Joao Doriguello, Christopher Vairogs, Nikolai Mirklin, and Daniel Mills.
