Accurate and bounded approximation of quantum correlation functions
Alexander van Lomwel, Florian Mintert
The exact classical simulation of non-integrable quantum systems rapidly becomes intractable beyond small system sizes, yet its role is central to predicting many-body dynamics. Ap…
Quantum information spreading in inhomogeneous spin ensembles
Rahul Gupta, Florian Mintert, Himadri Shekhar Dhar
We present a Krylov space based theoretical framework for modeling inhomogeneous spin ensembles with arbitrary distributions of spin frequencies and couplings. The framework is the…
Optimally Controlled Storage of a Qubit in an Inhomogeneous Spin Ensemble
Rahul Gupta, Florian Mintert, Himadri Shekhar Dhar
The storage of quantum information in spin-ensembles is limited by practically unavoidable inhomogeneous broadening, and the macroscopic number of spins in such an ensemble makes t…
Mitigating many-body quantum crosstalk with tensor-network robust control
Nguyen H. Le, Florian Mintert, Eran Ginossar
Quantum crosstalk poses a major challenge to scaling up quantum computations as its strength is typically unknown and its effect accumulates exponentially as system size grows. Her…
Analytically Exact Quantum Simulation of N-Body Interactions via Untunable Decentralized Hamiltonians for Implementing the Toric Code and Its Modifications
Haochen Zhao, Florian Mintert
We propose a new quantum simulation method for simulating N-body interactions, which are tensor products of N Pauli operators, in an analytically exact manner. This method iterativ…
Creation and manipulation of surface code defects with quantum optimal control
Omar Raii, Anirban Dey, Florian Mintert +1
The surface code is a spin-1/2 lattice system that can exhibit non-trivial topological order when defects are punctured in the lattice and thus can be used as a stabiliser code. Th…
Quantum control by effective counterdiabatic driving
Francesco Petiziol, Florian Mintert, Sandro Wimberger
We review a scheme for the systematic design of quantum control protocols based on shortcuts to adiabaticity in few-level quantum systems. The adiabatic dynamics is accelerated by…
Saturation of a spin 1/2 particle by generalized Local control
F. Mintert, M. Lapert, Y. Zhang +2
We show how to apply a generalization of Local control design to the problem of saturation of a spin 1/2 particle by magnetic fields in Nuclear Magnetic Resonance. The generalizati…
Quantum gates using electronic and nuclear spins of Yb in a magnetic field gradient
Kunling Wang, Michael Johanning, Mang Feng +2
An efficient scheme is proposed to carry out gate operations on an array of trapped Yb ions, based on a previous proposal using both electronic and nuclear degrees of freedom i…
