Christos, Dominic and Animesh's paper on quantum-enhanced estimation of multiple phase parameters has been published in Physical Review A. It looks at fundamental bounds on the performance of Gaussian states for estimation of multiple phase parameters and the advantage gained over multiple individual estimation strategies. The results also suggest that the optimal states for single phase estimation do not necessarily have the same performance when generalised to the estimation of multiple similar parameters.
Samuele and Jamie start their PhDs with us this week. Samuele joins us from the University of Turin. He will be working on quantum verification and is supported by the UK Quantum Technology hub NQIT. Jamie joins us from Aberystwyth University. He will be working on quantum-enhanced sensing, and is supported by the CDT on Diamond Technologies. Luke will continue his BSc project work in quantum biology on to an MSc with us.
`Quantum measurement' Physics Day on Sept. 28
Quantum optics paper in PRL
Paper on inferring quantum correlations from limited data outputs of quantum optics experiments is published in Physical Review Letters.
Theodoros worked on his PhD with Elham Kashefi at the University of Edinburgh's School of Informatics. He completed his PhD is early 2016, and his specialisation lies in the area of verification methods for quantum computation.
Tillmann's paper on the quantum enhanced estiamtion of non-commuting phases is published in Physical Review Letters. It shows that the simultaneous estimation of all three components of a magnetic field can be better than estimating them indivdually. It presents the measurements that come close to attaining the quantum limit. Our study also reveals that too much quantum entanglement may be detrimental to attaining the Heisenberg scaling in the estimation of unitarily generated parameters.

George completed his PhD from Oxford with Simon Benjamin and Andrew Briggs in 2014. He then spent a year at NTT in Japan. He was awarded the very presitgious 1851 Research Fellowship in 2015.
Paper on tomography of superconducting detectors published in New Journal of Physics
Latest paper with Ian Walmsley's group at Oxford, studying how photon numbers can be inferred from the continuous trace outputs of superconducting transition edge sensors.
Dominic Branford joins as PhD student
Dominic finished his undergraduate degree in Oxford, where he did a Master's project in quantum optics and quantum information.
Recognising outstanding refereeing
New Journal of Physics and the Institute of Physics are delighted to recognise the outstanding contribution of Animesh Datta towards New Journal of Physics’ peer review process during 2014.
The Editorial Board acknowledges Animesh Datta among the top 5% of referees and award this certificate of recognition to mark his dedication and professional excellence within the journal.
Christos Gagatsos joins us as a postdoc.
Christos completed his PhD in Brussels last year, working with Nicolas Cerf on quantum optics and quantum information theory.
The government announced £15 million towards training the next generation of quantum engineers with the creation of 'skills hubs' across the UK, working in partnership with industry to deliver career training for PhD students
National strategy for quantum technologies launched
The UK Government has invested £270 million in the UK National Quantum Technology Programme demonstrating its committment to create a valuable and sustainable quantum industry in the UK over the next two decades.
David Delpy, Chair of the UK National Quantum Technologies Programme Strategic Advisory Board, said: "This investment into Quantum Technologies represents the biggest single investment in a disruptive technology of the modern era. The UK has long been recognised as a world leader in quantum research, and we now have a real chance to build a solid and successful industrial base around that excellence in fundamental science and engineering. A concerted effort will allow for the creation of an industry that will deliver clear benefits back to the UK.
