Logical quantum processor based on reconfigurable atom arrays
Dolev Bluvstein, Simon J. Evered, Alexandra A. Geim +18
Suppressing errors is the central challenge for useful quantum computing, requiring quantum error correction for large-scale processing. However, the overhead in the realization of…
Quantum speedup for combinatorial optimization with flat energy landscapes
Madelyn Cain, Sambuddha Chattopadhyay, Jin-Guo Liu +3
Designing quantum algorithms with a speedup over their classical analogs is a central challenge in quantum information science. Motivated by recent experimental observations of a s…
Circumventing superexponential runtimes for hard instances of quantum adiabatic optimization
Benjamin F. Schiffer, Dominik S. Wild, Nishad Maskara +3
Classical optimization problems can be solved by adiabatically preparing the ground state of a quantum Hamiltonian that encodes the problem. The performance of this approach is det…
