Treespilation: Architecture- and State-Optimised Fermion-to-Qubit
Mappings | Quantum computers hold great promise for efficiently simulating Fermionic
systems, benefiting fields like quantum chemistry and materials science. To
achieve this, algorithms typically begin by choosing a Fermion-to-qubit mapping
to encode the Fermioinc problem in the qubits of a quantum computer. In this
work, we intr... | [

Experimental demonstration of scalable cross-entropy benchmarking to
detect measurement-induced phase transitions on a superconducting quantum
processor | Quantum systems subject to random unitary evolution and measurements at
random points in spacetime exhibit entanglement phase transitions which depend
on the frequency of these measurements. Past work has experimentally observed
entanglement phase transitions on near-term quantum computers, but the
characterization app... | [

New Pathways in Neutrino Physics via Quantum-Encoded Data Analysis | Ever-increasing amount of data is produced by particle detectors in their
quest to unveil the laws of Nature. The large data rate requires the use of
specialized triggers that promptly reduce the data rate to a manageable level;
however, in doing so, unexpected new phenomena may escape detection.
Additionally, the larg... | [

Evaluating Ground State Energies of Chemical Systems with Low-Depth
Quantum Circuits and High Accuracy | Solving electronic structure problems is considered one of the most promising
applications of quantum computing. However, due to limitations imposed by the
coherence time of qubits in the Noisy Intermediate Scale Quantum (NISQ) era or
the capabilities of early fault-tolerant quantum devices, it is vital to design
algor... | [

SPAM-Robust Multi-axis Quantum Noise Spectroscopy in Temporally
Correlated Environments | Characterizing temporally correlated (``non-Markovian'') noise is a key
prerequisite for achieving noise-tailored error mitigation and optimal device
performance. Quantum noise spectroscopy can afford quantitative estimation of
the noise spectral features; however, in its current form it is highly
vulnerable to impleme... | [
