Thermal lifetime of the centralized repetition code: From quantum annealing to social dynamics
Ari Mizel, Van Molino
There is an extensive body of research probing the potential of adiabatic quantum computation and quantum annealing to solve hard computational problems. This research endeavor is…
Renormalization method for proving frustration-free local spin chains are gapped
Ari Mizel, Van Molino
Key properties of a physical system depend on whether it is gapped, i.e. whether its spectral gap has a positive lower bound that is independent of system size. In quantum informat…
Right-sizing fluxonium against charge noise
Ari Mizel, Yariv Yanay
We analyze the charge-noise induced coherence time of the fluxonium qubit as a function of the number of array junctions in the device, . The pure dephasing rate decreases…
Proof of efficient, parallelized, universal adiabatic quantum computation
Ari Mizel
We give a careful proof that a parallelized version of adiabatic quantum computation can efficiently simulate universal gate model quantum computation. The proof specifies an expli…
Leggett-Garg test of superconducting qubit addressing the clumsiness loophole
Emilie Huffman, Ari Mizel
The Leggett-Garg inequality holds for any macrorealistic system that is being measured noninvasively. A violation of the inequality can signal that a system does not conform to our…
Gapped spin Hamiltonian motivated by quantum teleportation
Ari Mizel
We construct a Hamiltonian whose ground state encodes a time-independent emulation of quan- tum teleportation. We calculate properties of the Hamiltonian, using exact diagonalizati…

Quantum computation has revolutionary potential for speeding algorithms and for simulating quantum systems such as molecules. We report here a quantum computer design that performs…
Addressing the clumsiness loophole in a Leggett-Garg test of macrorealism
Mark M. Wilde, Ari Mizel
The rise of quantum information theory has lent new relevance to experimental tests for non-classicality, particularly in controversial cases such as adiabatic quantum computing su…
Could light harvesting complexes exhibit non-classical effects at room temperature?
Mark M. Wilde, James M. McCracken, Ari Mizel
Mounting experimental and theoretical evidence suggests that coherent quantum effects play a role in the efficient transfer of an excitation from a chlorosome antenna to a reaction…
Critically damped quantum search
Ari Mizel
Although measurement and unitary processes can accomplish any quantum evolution in principle, thinking in terms of dissipation and damping can be powerful. We propose a modificatio…
Geometrical Rabi transitions between decoupled quantum states
Xingxiang Zhou, Ari Mizel
A periodic perturbation such as a laser field cannot induce transitions between two decoupled states for which the transition matrix element vanishes. We show, however, that if in…

Ari Mizel, Daniel A. Lidar, Morgan Mitchell
We prove the equivalence between adiabatic quantum computation and quantum computation in the circuit model. An explicit adiabatic computation procedure is given that generates a g…

Ari Mizel, M. W. Mitchell, Marvin L. Cohen
We formulate a novel ground state quantum computation approach that requires no unitary evolution of qubits in time: the qubits are fixed in stationary states of the Hamiltonian. T…
