Preprints and technical reports from CQuIC researchers across all four research areas.
CQuIC Papers
CQuIC researchers regularly produce technical reports and preprints deposited on arXiv.org prior to formal peer review. These reports represent the current research frontier across quantum information & computation, quantum control & measurement, quantum optics & communication, and quantum metrology.
Full Listing
We develop quantum error-correcting codes and decoding algorithms tailored to non-Markovian noise models arising in solid-state qubit platforms, demonstrating improved logical error rates over standard depolarising-noise codes.
Classical shadow tomography is integrated into variational quantum eigensolver (VQE) workflows, reducing measurement overhead by an order of magnitude while preserving accuracy in ground-state energy estimation.
Gradient-ascent pulse engineering (GRAPE) is extended to high-dimensional qudit systems in alkali-metal atoms, achieving average gate fidelities above 99.5% for d = 16 dimensional Hilbert spaces relevant to quantum error correction.
Collective-spin squeezed states produced via cavity QED back-action are deployed in a Ramsey interferometer, achieving phase sensitivity 8 dB below the standard quantum limit with 2,000 cesium atoms.
We analyse quantum repeater architectures that interface photonic qubits with heterogeneous atomic ensembles, deriving throughput and fidelity bounds and proposing a protocol compatible with current telecom-wavelength photon sources.
We characterise the interplay between quantum coherence and thermodynamic constraints, establishing necessary and sufficient conditions for coherence interconversion under thermal operations and connecting results to quantum heat-engine efficiency.
An adaptive Bayesian protocol for quantum state tomography is presented that selects future measurements based on current posterior uncertainty, reducing the number of measurements required for a given fidelity target by a factor of three.
