Dissipative preparation of injective tensor network states
Drishti Baruah, Georgios Styliaris, J. Ignacio Cirac +1
The preparation of tensor network states is a fundamental prerequisite for a wide range of quantum simulation tasks. While many unitary protocols for preparing these states have be…
Probing Off-diagonal Eigenstate Thermalization with Tensor Networks
Maxine Luo, Rahul Trivedi, Mari Carmen Bañuls +1
Energy filter methods in combination with quantum simulation can efficiently access the properties of quantum many-body systems at finite energy densities [Lu et al. PRX Quantum 2,…
Phase-Sensitive Quantum Measurement without Controlled Operations
Yilun Yang, Arthur Christianen, Mari Carmen Bañuls +2
Many quantum algorithms rely on the measurement of complex quantum amplitudes. Standard approaches to obtain the phase information, such as the Hadamard test, give rise to large ov…
Matrix product state approximations to quantum states of low energy variance
Kshiti Sneh Rai, J. Ignacio Cirac, Álvaro M. Alhambra
We show how to efficiently simulate pure quantum states in one dimensional systems that have both finite energy density and vanishingly small energy fluctuations. We do so by study…
Preparation of matrix product states with log-depth quantum circuits
Daniel Malz, Georgios Styliaris, Zhi-Yuan Wei +1
We consider the preparation of matrix product states (MPS) on quantum devices via quantum circuits of local gates. We first prove that faithfully preparing translation-invariant no…
Fermionic matter-wave quantum optics with cold-atom impurity models
Bennet Windt, Miguel Bello, Eugene Demler +1
Motivated by recent cold-atom realisations of matter-wave waveguide QED, we study simple fermionic impurity models and discuss fermionic analogues of several paradigmatic phenomena…
