A general quantum algorithm for open quantum dynamics demonstrated with the Fenna-Matthews-Olson complex [PDF]
Using quantum algorithms to simulate complex physical processes and correlations in quantum matter has been a major direction of quantum computing research, towards the promise of a quantum advantage over classical approaches.

Quantum physics and biology: the local wavefunction approach
Abstract Is there a single linearly evolving Wave Function of the Universe that is able to lead to all the nonlinearities we see around us? This proposal seems a priori highly implausible. I claim that instead, in the real Universe, generically only local wave functions exist.

Primitive Ontology and the Structure of Fundamental Physical Theories [PDF]
For a long time, it was believed that it was impossible to be realist about quantum mechanics. It took quite a while for the researchers in the foundations of physics, beginning with John Stuart Bell (1987), to convince others that such an alleged ...

Investigations in Quantum Computing: Causality and Graph Isomorphism [PDF]
In this thesis I explore two different types of limits on the time complexity of quantum computation---that is, limits on how much time is required to perform a given class of quantum operations on a quantum system. Upper limits can be found by explicit

Advances in Modeling of Noisy Quantum Computers: Spin Qubits in Semiconductor Quantum Dots
The new quantum era is expected to have an unprecedented social impact, enabling the research of tomorrow in several pivotal fields. These perspectives require a physical system able to encode, process and store for a sufficiently long amount of time the

Toy Models of a Nonassociative Quantum Mechanics
Toy models of a nonassociative quantum mechanics are presented. The Heisenberg equation of motion is modified using a nonassociative commutator. Possible physical applications of a nonassociative quantum mechanics are considered.

From Rotations to Unitaries: Reversible Quantum Processes and the Emergence of the SU(2)−SO(3) Homomorphism [PDF]
We present an operational reconstruction of the well-known two-to-one homomorphism between the groups SU(2) and SO(3), grounded in the physical description of quantum state preparation and evolution.

Socio-Economic Sciences: Beyond Quantum Math-like Formalisms
Since the beginning of the 21st century, a new interdisciplinary research movement has started, which aims at developing quantum math-like (or simply quantum-like) models to provide an explanation for a variety of socio-economic processes and human ...
