1- Photon number discrimination without photon counting (theory and experiment)
In this talk I want to present progress of our quantum optics laboratory. Our laboratory was built in the summer 2013. During the past year we've performed number of beautiful experiments. One of the featured experiments is "Quantum vampire" which demonstrates non-local properties of the annihilation operator. This beautiful effect predicts that if you take particular number of photons from the part of the light beam there will be now shadow.
Quantum information is a very valuable, but also very fragile resource.
The Quantum Innovators workshop will bring together the most promising young researchers in quantum physics and engineering for a three-day conference aimed at exploring the frontier of our field.
ETSI, in partnership with the Institute for Quantum Computing (IQC), is pleased to invite you to the second IQC/ETSI Quantum-Safe Crypto Workshop. The event will be held in Ottawa, Canada, on 6th – 7th October, 2014. This workshop will bring together the diverse communities that will need to co-operate to standardize and deploy the next-generation cryptographic infrastructure, in particular, one that will be secure against emerging quantum computing technologies. The event agenda will be announced Early September.
Nanowires offer exciting opportunities in quantum optics. Using quantum dots in semiconducting nanowires, we demonstrate the generation of single photons as well as pairs of entangled photons. Making electrical contacts to semiconducting nanowires, we make a single quantum dot LED where electroluminescence from a single quantum dot can be studied. Similar devices operated as photodiodes enable the operation of single nanowire avalanche photodiodes.
We develop a method for approximate synthesis of single--qubit rotations of the form e^{-i f(\phi_1,\ldots,\phi_k)X} that is based on the Repeat-Until-Success (RUS) framework for quantum circuit synthesis. We demonstrate how smooth computable functions, f, can be synthesized from two basic primitives. This synthesis approach constitutes a manifestly quantum form of arithmetic that differs greatly from the approaches commonly used in quantum algorithms.
Introducing the next installment of the Quantum Industry Lecture Series (QuILS). Nathan Wiebe, a former IQC postdoctoral fellow who is currently working at Microsoft, will talk to us about what it's like to work in research for a technological powerhouse.
I will discuss some new results we have recently obtained for the
problem of quantum states discrimination by Local Operations and
National Physical Laboratory (NPL) is developing a measurement infrastructure for traceably characterising the quantum optical components of Quantum Key Distribution (QKD) systems, one of the most commercially advanced quantum technologies, and among the first to directly harness the peculiar laws of quantum physics.
