Computable fermionic non-Gaussianity from the covariance matrix
Poetri Sonya Tarabunga, Bernhard Jobst, Raúl Morral-Yepes +4
Fermionic non-Gaussianity, or fermionic magic, is a key resource underlying the computational complexity of fermionic quantum systems, yet tractable and operationally meaningful wa…
Benchmark of quantum algorithms for ground state preparation in the presence of noise
Daniel Molpeceres, Sirui Lu, J. Ignacio Cirac +1
We compare the performance of representative cooling, adiabatic, and optimization algorithms for ground-state preparation in the presence of noise. Using an exactly solvable family…
Disentangling strategies and entanglement transitions in unitary circuit games with matchgates
Raúl Morral-Yepes, Marc Langer, Adam Gammon-Smith +2
In unitary circuit games, two competing parties, an "entangler" and a "disentangler", can induce an entanglement phase transition in a quantum many-body system. The transition occu…
Quantum algorithms for cooling: a simple case study
Daniel Molpeceres, Sirui Lu, J. Ignacio Cirac +1
Preparation of low-energy quantum many-body states has a wide range of applications in quantum information processing and condensed matter physics. Quantum cooling algorithms offer…
Compressed quantum metrology for the Ising Hamiltonian
W. L. Boyajian, M. Skotiniotis, W. Dür +1
We show how quantum metrology protocols that seek to estimate the parameters of a Hamiltonian that exhibits a quantum phase transition can be efficiently simulated on an exponentia…
Compressed quantum simulation of the Ising model
B. Kraus
In [R. Jozsa, B. Kraus, A. Miyake, J. Watrous, Proc. R. Soc. A {\bf 466}, 809-830 (2010)] it has been shown that a match gate circuit running on n qubits can be compressed to a uni…
Decoherence of many-body systems due to many-body interactions
T. Carle, H. J. Briegel, B. Kraus
We study a spin-gas model, where N_S system qubits are interacting with N_B bath qubits via many-body interactions. We consider multipartite Ising interactions and show how the eff…
On the role of memory errors in quantum repeaters
L. Hartmann, B. Kraus, H. -J. Briegel +1
We investigate the influence of memory errors in the quantum repeater scheme for long-range quantum communication. We show that the communication distance is limited in standard op…
