Quantum sensing

Advance quantum integrated photonics within the Quantum Sensing and Computing Group. Develop quantum-sensing concepts and their practical implementation, with particular interest in the design, fabrication and testing of photonic devices and circuits. Applications are made on the employer’s recruitment portal; no closing date is stated. Initial appointment up to 24 months, with extensions dependent on performance and funding.

Sahand Tabatabaei presents SQUINT, a sensing platform that combines molecular electron spins, sensitive mechanical detection and control of spin interactions. Molecular sensors can be chemically adjusted and positioned near targets, offering flexibility that defects fixed inside a solid host cannot provide. The work uses a modified XYXY decoupling sequence to reduce dipolar interactions despite uneven control fields. In a sample containing roughly 100 trityl radicals, the reported coherence time reaches about 400 microseconds. These longer-lived spins enable frequency-selective measurements o
