Analog-Digital Quantum Computing with Quantum Annealing Processors
Rahul Deshpande, Majid Kheirkhah, Chris Rich +12
Quantum annealing processors typically control qubits in unison, attenuating quantum fluctuations uniformly until the applied system Hamiltonian is diagonal in the computational ba…
Computational Complexity and Simulability of Non-Hermitian Quantum Dynamics
Brian Barch, Daniel Lidar
Non-Hermitian (NH) quantum systems demonstrate striking differences from their Hermitian counterparts, leading to claims of NH advantage in areas ranging from metrology to entangle…
Locality, Correlations, Information, and non-Hermitian Quantum Systems
Brian Barch
Local non-Hermitian (NH) quantum systems generically exhibit breakdown of Lieb-Robinson (LR) bounds, motivating study of whether new locality measures might shed light not seen by…
Scrambling and operator entanglement in local non-Hermitian quantum systems
Brian Barch, Namit Anand, Jeffrey Marshall +2
The breakdown of Lieb-Robinson bounds in local, non-Hermitian quantum systems opens up the possibility for a rich landscape of quantum many-body phenomenology. We elucidate this by…
Low overhead universality and quantum supremacy using only -control
Brian Barch, Razieh Mohseninia, Daniel Lidar
We consider a model of quantum computation we call "Varying-" (V), defined by applying controllable -diagonal Hamiltonians in the presence of a uniform and constant extern…
