Photonic Entanglement for a Quantum Repeater
… one to distribute a random secret key between two users that are connected through a public channel without revealing information to unauthorized parties. If a message is encrypted with the one time pad (a well-known crytography algorithm) using secret keys created by QKD, then the ciphertext …

Coherence, Dephasing, and Quantum Interference in Colloidal Perovskite Nanocrystals
As the development of photonic quantum technologies continues to be pushed forward, the need for a source of quantum light, the so-called quantum emitter, has been ever-growing. The requirements for a quantum emitter are onerous: indistinguishable photon or entangled photon pairs need to be …

A nanophotonic platform for the tin-vacancy centre
Quantum networking will enable quantum devices to exchange information. As of today, the technology is still at an early research stage, and entanglement has only been demonstrated at low rates and between a few nodes. Among the concerted efforts to establish new scalable architectures, colour …

Growth, characterization and implementation of semiconductor sources of highly entangled photons
Sources of single and polarization-entangled photons are an essential component in a variety of potential quantum information applications. Suitable emitters need to generate photons deterministically and at fast repetition rates, with highest degrees of single-photon purity, entanglement and …

A Quantum Light Source for Quantum Information Applications in the Telecom C-Band
… highly indistinguishable single and entangled photons. A key factor in the development of this technology is the operation over the standard telecommunication optical fibre network infrastructure, where the minimum absorption wavelength window is centred on the telecom C-band (1530 – 1565 nm). …

Quantum dot-based Entangled-Light Emitting Diodes (E-LED) for quantum relays
Sources of entangled pairs of photons can be used for encoding signals in quantum-encrypted communications, allowing a sender, Alice, and a receiver, Bob, to exchange keys without the possibility of eavesdropping. In fact, any quantum information system would require single and entangled photons to …

Telecom Wavelength Quantum Devices
… as sub-Poissonian sources of entangled photon pairs. To improve the utility of a QD light source, it would be advantageous to extend their emission further into the near infrared, into the low absorption wavelength windows utilised in long-haul optical telecommunication. Initial …

Optimized resources for efficient optical quantum information processing and sensing
… detector characterization, and multi-photon processing. For each application, we examine the underlying quantum resource states and quantum technology resources. Careful attention is paid to how these resources can be optimized to maximize the efficiency of the overarching application …
