Derandomised tensor product gap amplification for quantum Hamiltonians
Thiago Bergamaschi, Tony Metger, Thomas Vidick +1
The quantum PCP conjecture asks whether it is QMA-hard to distinguish between high- and low-energy Hamiltonians even when the gap between "high" and "low" energy is large (constant…

Improved Product-state Approximation Algorithms for Quantum Local Hamiltonians
Thiago Bergamaschi
The ground state energy and the free energy of Quantum Local Hamiltonians are fundamental quantities in quantum many-body physics, however, it is QMA-Hard to estimate them in gener…
