Small logical qubit architecture based on strong interactions and many-body dynamical decoupling
Eliot Kapit, Vadim Oganesyan
We propose a novel superconducting logical qubit architecture, called the Cold Echo Qubit (CEQ), which is capable of preserving quantum information for much longer timescales than…
Realization of two-qutrit quantum algorithms on a programmable superconducting processor
Tanay Roy, Ziqian Li, Eliot Kapit +1
Processing quantum information using quantum three-level systems or qutrits as the fundamental unit is an alternative to contemporary qubit-based architectures with the potential t…
Error-divisible two-qubit gates
David Rodriguez Perez, Paul Varosy, Ziqian Li +3
We introduce a simple, widely applicable formalism for designing "error-divisible" two qubit gates: a quantum gate set where fractional rotations have proportionally reduced error…
Tomography in the presence of stray inter-qubit coupling
Tanay Roy, Ziqian Li, Eliot Kapit +1
Tomography is an indispensable part of quantum computation as it enables diagnosis of a quantum process through state reconstruction. Existing tomographic protocols are based on de…
Theoretical survey of unconventional quantum annealing methods applied to adifficult trial problem
Zhijie Tang, Eliot Kapit
We consider a range of unconventional modifications to Quantum Annealing (QA), applied to an artificial trial problem with continuously tunable difficulty. In this problem, inspire…
K-spin Hamiltonian for quantum-resolvable Markov decision processes
Eric B. Jones, Peter Graf, Eliot Kapit +1
The Markov decision process is the mathematical formalization underlying the modern field of reinforcement learning when transition and reward functions are unknown. We derive a ps…
