Testing measurement-based computational phases of quantum matter on a quantum processor
Ryohei Weil, Dmytro Bondarenko, Arnab Adhikary +1
Many symmetry protected or symmetry enriched phases of quantum matter have the property that every ground state in a given such phase endows measurement based quantum computation w…
Advantage of Warm Starts for Electron-Phonon Systems on Quantum Computers
Arnab Adhikary, S. E. Skelton, Alberto Nocera +1
Simulating electron-phonon interactions on quantum computers remains challenging, with most algorithmic effort focused on Hamiltonian simulation and circuit optimization. In this w…
Sub-Riemannian geometry of measurement based quantum computation
Lukas Hantzko, Arnab Adhikary, Robert Raussendorf
The computational power of quantum phases of matter with symmetry can be accessed through local measurements, but what is the most efficient way of doing so? In this work, we show…
Measurement-based quantum computation in symmetry protected topological states of one-dimensional integer spin systems
Wang Yang, Arnab Adhikary, Robert Raussendorf
In this work, we generalize the algebraic framework for measurement-based quantum computation (MBQC) in one-dimensional symmetry protected topological states recently developed in…
Counter-intuitive yet efficient regimes for measurement based quantum computation on symmetry protected spin chains
Arnab Adhikary, Wang Yang, Robert Raussendorf
Quantum states picked from non-trivial symmetry protected topological (SPT) phases have computational power in measurement based quantum computation. This power is uniform across S…
Measurement-based quantum computation in finite one-dimensional systems: string order implies computational power
Robert Raussendorf, Wang Yang, Arnab Adhikary
We present a new framework for assessing the power of measurement-based quantum computation (MBQC) on short-range entangled symmetric resource states, in spatial dimension one. It…
Emergent SU(2) conformal symmetry in the spin-1/2 Kitaev-Gamma chain with a Dzyaloshinskii-Moriya interaction
Wang Yang, Alberto Nocera, Chao Xu +3
We study the one-dimensional spin-1/2 Kitaev-Gamma model with a bond-dependent Dzyaloshinskii-Moriya (DM) interaction, which can be induced by an electric field applied in the thir…
Quantum Signaling to the Past Using P-CTCS
Soumik Ghosh, Arnab Adhikary, Goutam Paul
Closed Timelike Curves (CTCs) are intriguing relativistic objects that allow for time travel to the past and can be used as computational resources. In Deutschian Closed Timelike C…
Revisiting Integer Factorization using Closed Timelike Curves
Soumik Ghosh, Arnab Adhikary, Goutam Paul
Closed Timelike Curves are relativistically valid objects allowing time travel to the past. Treating them as computational objects opens the door to a wide range of results which c…
