Robust quantum reservoir computers for forecasting chaotic dynamics: generalized synchronization and stability
Osama Ahmed, Felix Tennie, Luca Magri
We show that recurrent quantum reservoir computers (QRCs) and their recurrence-free architectures (RF-QRCs) are robust tools for learning and forecasting chaotic dynamics from time…
Optimal training of finitely-sampled quantum reservoir computers for forecasting of chaotic dynamics
Osama Ahmed, Felix Tennie, Luca Magri
In the current Noisy Intermediate Scale Quantum (NISQ) era, the presence of noise deteriorates the performance of quantum computing algorithms. Quantum Reservoir Computing (QRC) is…
Quantum Computing for nonlinear differential equations and turbulence
Felix Tennie, Sylvain Laizet, Seth Lloyd +1
A large spectrum of problems in classical physics and engineering, such as turbulence, is governed by nonlinear differential equations, which typically require high-performance com…
Prediction of chaotic dynamics and extreme events: A recurrence-free quantum reservoir computing approach
Osama Ahmed, Felix Tennie, Luca Magri
In chaotic dynamical systems, extreme events manifest in time series as unpredictable large-amplitude peaks. Although deterministic, extreme events appear seemingly randomly, which…
Solving nonlinear differential equations on Quantum Computers: A Fokker-Planck approach
Felix Tennie, Luca Magri
For quantum computers to become useful tools to physicists, engineers and computational scientists, quantum algorithms for solving nonlinear differential equations need to be devel…
Procedure for improving cross-resonance noise resistance using pulse-level control
David Danin, Felix Tennie
Current implementations of superconducting qubits are often limited by the low fidelities of multi-qubit gates. We present a reproducible and runtime-efficient pulse-level approach…
Mode Entanglement in Fermionic and Bosonic Harmonium
Jan Ole Ernst, Felix Tennie
Mode entanglement in many-body quantum systems is an active area of research. It provides crucial insight into the suitability of many-body systems for quantum information processi…
Quantum Computers for Weather and Climate Prediction: The Good, the Bad and the Noisy
Felix Tennie, Tim Palmer
Over the past few years, quantum computers and quantum algorithms have attracted considerable interest and attention from numerous scientific disciplines. In this article, we aim t…
Refrigeration with Indefinite Causal Orders on a Cloud Quantum Computer
David Felce, Vlatko Vedral, Felix Tennie
We demonstrate non-classical cooling on the IBMq cloud quantum computer. We implement a recently proposed refrigeration protocol which relies upon indefinite causal order for its q…
Quantum algorithm for nonlinear differential equations
Seth Lloyd, Giacomo De Palma, Can Gokler +5
Quantum computers are known to provide an exponential advantage over classical computers for the solution of linear differential equations in high-dimensional spaces. Here, we pres…
Universal upper bounds on the Bose-Einstein condensate and the Hubbard star
Felix Tennie, Vlatko Vedral, Christian Schilling
For hard-core bosons on an arbitrary lattice with sites and independent of additional interaction terms we prove that the hard-core constraint itself already enforces a uni…
Pinning of fermionic occupation numbers: Higher spatial dimensions and spin
Felix Tennie, Vlatko Vedral, Christian Schilling
The role of the generalized Pauli constraints (GPCs) in higher spatial dimensions and by incorporating spin degrees of freedom is systematically explored for a system of interactin…
Pinning of Fermionic Occupation Numbers: General Concepts and One Dimension
Felix Tennie, Daniel Ebler, Vlatko Vedral +1
Analytical evidence for the physical relevance of generalized Pauli constraints (GPCs) has recently been provided in [PRL 110, 040404]: Natural occupation numbers $\vecλ\equiv (λ_i…
Influence of the Fermionic Exchange Symmetry beyond Pauli's Exclusion Principle
Felix Tennie, Vlatko Vedral, Christian Schilling
Pauli's exclusion principle has a strong impact on the properties of most fermionic quantum systems. Remarkably, the fermionic exchange symmetry implies further constraints on the…
Consistent matter couplings for Plebanski gravity
Felix Tennie, Mattias N. R. Wohlfarth
We develop a scheme for the minimal coupling of all standard types of tensor and spinor field matter to Plebanski gravity. This theory is a geometric reformulation of vacuum genera…
