Developments in superconducting erasure qubits for hardware-efficient quantum error correction
Maria Violaris, Luciana Henaut, James Wills +3
Quantum computers are inherently noisy, and a crucial challenge for achieving large-scale, fault-tolerant quantum computing is to implement quantum error correction. A promising di…
Quantum observers can communicate across multiverse branches
Maria Violaris
It is commonly thought that observers in distinct branches of an Everettian multiverse cannot communicate without violating the linearity of quantum theory. Here we show a countere…
Entangling Disciplines: Causality, Entropy and Time-Travel Paradoxes on a Quantum Computer
Maria Violaris
Merging disciplines has led to incredible learnings and breakthroughs throughout history, including the discovery of quantum computing: a cross between computation and quantum phys…
Counterfactuals in Macroscopic Quantum Physics: Irreversibility, Measurement and Locality
Maria Violaris
Can quantum theory be applied on all scales? While there are many arguments for the universality of quantum theory, this question remains a subject of debate. It is unknown how far…
Universal quantum theory contains twisted logic
Francesco Atzori, Enrico Rebufello, Maria Violaris +9
Quantum theory is notoriously counterintuitive, and yet remains entirely self-consistent when applied universally. Here we uncover a new manifestation of its unusual consequences.…
Impossibility of universal work extraction from coherence: Reconciling axiomatic and resource-theory approaches
Samuel Plesnik, Maria Violaris
We compare how the impossibility of a universal work extractor from coherence arises from different approaches to quantum thermodynamics: an explicit protocol accounting for all re…
A Physics Lab Inside Your Head: Quantum Thought Experiments as an Educational Tool
Maria Violaris
Thought experiments are where logical reasoning meets storytelling, catalysing progress in quantum science and technology. Schrödinger's famous cat brought quantum science to the p…
Comparing coherent and incoherent models for quantum homogenization
Anna Beever, Maria Violaris, Chiara Marletto +1
Here we investigate the role of quantum interference in the quantum homogenizer, whose convergence properties model a thermalization process. In the original quantum homogenizer pr…
The irreversibility cost of purifying Szilard's engine: Is it possible to perform erasure using the quantum homogenizer?
Maria Violaris, Chiara Marletto
Erasure is fundamental for information processing. It is also key in connecting information theory and thermodynamics, as it is a logically irreversible task. We provide a new angl…
Transforming pure and mixed states using an NMR quantum homogeniser
Maria Violaris, Gaurav Bhole, Jonathan A. Jones +2
The universal quantum homogeniser can transform a qubit from any state to any other state with arbitrary accuracy, using only unitary transformations to perform this task. Here we…
