Observing relativistic trajectories of single photons
Sayantan Das, Daniel S. Dahl, Daniel Peace +6
While the standard interpretation of quantum mechanics does not assign definite trajectories to particles, the Bohmian interpretation does. Only recently has an operational method…
Generalised quantum interference
Sebastian Malewicz, Laura Serino, Marcelo P. de Almeida +6
Hong-Ou-Mandel interference is one of the clearest signatures of quantum behaviour: two identical photons meeting at a beam splitter always leave together. Here we demonstrate that…
Photonic Quantum-Accelerated Machine Learning
Markus Rambach, Abhishek Roy, Alexei Gilchrist +4
Machine learning is widely applied in modern society, but has yet to capitalise on the unique benefits offered by quantum resources. Boson sampling -- a quantum-interference based…
Quantum mechanics can find a needle in a haystack every time
Fatemeh Mohit, Joshua Guanzon, Jaden McKinlay +5
Grover's algorithm is one of the pioneering demonstrations of the advantages of quantum computing over its classical counterpart, providing - at most - a quadratic speed-up over th…
Self-guided tomography of time-frequency qudits
Laura Serino, Markus Rambach, Benjamin Brecht +2
High-dimensional time-frequency encodings have the potential to significantly advance quantum information science; however, practical applications require precise knowledge of the…
Randomness-free Test of Non-classicality: a Proof of Concept
Zhonghua Ma, Markus Rambach, Kaumudibikash Goswami +3
Quantum correlations and non-projective measurements underlie a plethora of information-theoretic tasks, otherwise impossible in the classical world. Existing schemes to certify su…
Efficient Quantum State Tracking in Noisy Environments
Markus Rambach, Akram Youssry, Marco Tomamichel +1
Quantum state tomography, which aims to find the best description of a quantum state -- the density matrix, is an essential building block in quantum computation and communication.…
Efficient, ever-ready quantum memory at room temperature for single photons
Anthony C. Leung, W. Y. Sarah Lau, Aaron D. Tranter +6
Efficient quantum memories will be an essential building block of large scale networked quantum systems and provide a link between flying photonic qubits and atomic or quasi-atomic…
A Bright Source of Telecom Single Photons Based on Quantum Frequency Conversion
Christopher L. Morrison, Markus Rambach, Zhe Xian Koong +10
On-demand indistinguishable single photon sources are essential for quantum networking and communication. Semiconductor quantum dots are among the most promising candidates, but th…
Precisely determining photon-number in real-time
Leonardo Assis Morais, Till Weinhold, Marcelo Pereira de Almeida +7
Superconducting transition-edge sensors (TES) are extremely sensitive microcalorimeters used as photon detectors with unparalleled energy resolution. They have found application fr…
Robust and Efficient High-dimensional Quantum State Tomography
Markus Rambach, Mahdi Qaryan, Michael Kewming +3
The exponential growth in Hilbert space with increasing size of a quantum system means that accurately characterising the system becomes significantly harder with system dimension…
Coherent Dynamics in Quantum Emitters under Dichromatic Excitation
Z. X. Koong, E. Scerri, M. Rambach +8
We characterize the coherent dynamics of a two-level quantum emitter driven by a pair of symmetrically-detuned phase-locked pulses. The promise of dichromatic excitation is to spec…
Highly tunable quantum light from moiré trapped excitons
Hyeonjun Baek, Mauro Brotons-Gisbert, Zhe Xian Koong +5
Photon antibunching, a hallmark of quantum light, has been observed in the correlations of light from isolated atomic and atomic-like solid-state systems. Two-dimensional semicondu…
Fundamental Limits to Coherent Photon Generation with Solid-State Atomlike Transitions
Zhe-Xian Koong, Dale Scerri, Markus Rambach +5
Coherent generation of indistinguishable single photons is crucial for many quantum communication and processing protocols. Solid-state realizations of two-level atomic transitions…
Hectometer Revivals of Quantum Interference
Markus Rambach, W. Y. Sarah Lau, Simon Laibacher +3
Cavity-enhanced single photon sources exhibit mode-locked biphoton states with comb-like correlation functions. Our ultrabright source additionally emits either single photon pairs…
Sub-Megahertz Single Photon Source
Markus Rambach, Aleksandrina Nikolova, Till J. Weinhold +1
We report 100% duty cycle generation of sub-MHz single photon pairs at the Rubidium D line using cavity-enhanced spontaneous parametric downconversion. The temporal intensity c…
Universal digital quantum simulation with trapped ions
B. P. Lanyon, C. Hempel, D. Nigg +11
A digital quantum simulator is an envisioned quantum device that can be pro- grammed to efficiently simulate any other local system. We demonstrate and investigate the digital appr…
