Distributed fault-tolerant quantum memories over a 2xL array of qubit modules
Edwin Tham, Min Ye, Ilia Khait +2
We propose an architecture for a quantum memory distributed over a array of modules equipped with a cyclic shift implemented via flying qubits. The logical information…
Variational Quantum Eigensolvers in the Era of Distributed Quantum Computers
Ilia Khait, Edwin Tham, Dvira Segal +1
The computational power of a quantum computer is limited by the number of qubits available for information processing. Increasing this number within a single device is difficult; i…
Hall map and breakdown of Fermi liquid theory in the vicinity of a Mott insulator
Ilia Khait, Sauri Bhattacharyya, Abhisek Samanta +1
The Hall coefficient exhibits anomalous behavior in lightly doped Mott insulators. For strongly interacting electrons its computation has been challenged by analytical and numerica…
Preferred Interaction Ranges in Neutral-Atom Arrays in the Presence of Noise
David C. Spierings, Edwin Tham, Aharon Brodutch +1
Successful execution of a quantum information processing (QIP) task on a quantum processing device depends on the availability of high-quality entangling gates. Two important goals…
Simulating time evolution on distributed quantum computers
Finn Lasse Buessen, Dvira Segal, Ilia Khait
We study a variation of the Trotter-Suzuki decomposition, in which a Hamiltonian exponential is approximated by an ordered product of two-qubit operator exponentials such that the…
Quantum circuit optimization for multiple QPUs using local structure
Edwin Tham, Ilia Khait, Aharon Brodutch
Interconnecting clusters of qubits will be an essential element of scaling up future quantum computers. Operations between quantum processing units (QPUs) are usually significantly…
Krein-unitary Schrieffer-Wolff transformation and band touchings in bosonic Bogoliubov-de Gennes and other Krein-Hermitian Hamiltonians
Geremia Massarelli, Ilia Khait, Arun Paramekanti
Krein-Hermitian Hamiltonians, i.e., Hamiltonians Hermitian with respect to an indefinite inner product, have emerged as an important class of non-Hermitian Hamiltonians in physics,…
Optimal control of quantum thermal machines using machine learning
Ilia Khait, Juan Carrasquilla, Dvira Segal
Identifying optimal thermodynamical processes has been the essence of thermodynamics since its inception. Here, we show that differentiable programming (DP), a machine learning (ML…
Universal Bounds on Fluctuations in Continuous Thermal Machines
Sushant Saryal, Matthew Gerry, Ilia Khait +2
We study bounds on ratios of fluctuations in steady-state time-reversal heat engines controlled by multi affinities. In the linear response regime, we prove that the relative fluct…
Characterizing spin-one Kitaev quantum spin liquids
Ilia Khait, P. Peter Stavropoulos, Hae-Young Kee +1
Material realizations of the bond-dependent Kitaev interactions with =1/2 local moments have vitalized the research in quantum spin liquids. Recently, it has been proposed that…
Dirac magnons in a honeycomb lattice quantum XY magnet CoTiO3
Bo Yuan, Ilia Khait, Guo-Jiun Shu +5
The discovery of massless Dirac electrons in graphene and topological Dirac-Weyl materials has prompted a broad search for bosonic analogues of such Dirac particles. Recent experim…
Emergent non-Fermi-liquid phenomena in multipolar quantum impurity systems
Adarsh S. Patri, Ilia Khait, Yong Baek Kim
Discovery of novel spin-orbital entangled quantum ground states paves an important avenue for controllable quantum materials via unique couplings to the lattice and other external…
Anisotropic Magnetoresistance in Multiband Systems: 2DEGs and Polar Metals at Oxide Interfaces
Nazim Boudjada, Ilia Khait, Arun Paramekanti
Low density two-dimensional electron gases (2DEGs) with spin-orbit coupling are highly sensitive to an in-plane magnetic field, which impacts their Fermi surfaces and transport pro…
Doped Kondo chain, a heavy Luttinger liquid
Ilia Khait, Patrick Azaria, Claudius Hubig +2
The one dimensional Kondo Lattice model is studied by Density Matrix Renormalization Group away from half-filling. We find signatures of a Heavy Tomonaga-Luttinger Liquid (…
Spin transport of weakly disordered Heisenberg chain at infinite temperature
Ilia Khait, Snir Gazit, Norman Y. Yao +1
We study the disordered Heisenberg spin chain, which exhibits many body localization at strong disorder, in the weak to moderate disorder regime. A continued fraction calculation o…
