Quantum error mitigation (QEM) is a class of promising techniques capable reducing the computational variational quantum algorithms tailored for current noisy intermediate-scale computers. The recently proposed permutation-based methods are practically attractive, since they do not rely on any a pr...

Human Machine Interaction systems are able to perceive facial expressions more naturally and reliably. In this paper, we introduced a new idea to recognize facial expression by selecting the most discriminative facial regions relying on facial expression appearance. The proposed approach is based on the prior knowledge of psychology studies which show that only some facial regions are descripti...

In the past week three young people have come to my door, with lanyards and branded T shirts, asking me to pledge regular donations to charity. Each represented a big, national, medical charity, the kinds withmarketingmanagers and campaign teams. I said no to each one, which prompted two of them to enter into sales pitches about how helping to set up a direct debit would “just take a minute.” B...

Research in collaborative editing tends to have been undertaken in isolation rather than as part of a general information or application infrastructure. Our goal is to develop a universal information platform that can support collaboration in a range of application domains. Since not all user groups have the same conventions and not all tasks have the same requirements, this implies that it sho...

We have investigated a new radiation pressure trap which relies on optical pumping and does not require any magnetic field. It employs six circularly polarized divergent beams and works on the red of a Jg −→ Je = Jg + 1 atomic transition with Jg ≥ 1/2. We have demonstrated this trap with cesium atoms from a vapour cell using the 852 nm Jg = 4 −→ Je = 5 resonance transition. The trap contained u...
