• From Laser to Market: Optics Conference Continues

  …l implementation has to be attached to real infrastructure and current challenges" explained Mr. Gleim. The particularities of this R&D is that when transmitting data in the quantum state, we use so-called "side frequencies", which compared to other approaches give a smaller error rate and maximum bandwith (read more about it here). Specialists from the company are…

• What to Do if Photons Entangle You?

  …urpose. Currently researchers aim to create quantum memory devices for the repeaters. The process of distance communication requires the interaction of light and matter, as quantum state "transfers" to the particle state. One of the promising techniques is when a photon interacts with plenty of atoms, so called "atom assembly." Thanks to that, one can record and r…

• Researchers Find Way to Enhance Photon Entanglement

  …sion, quantum teleportation and are considered to be instrumental to the rise of optical computing. Quantum entanglement occurs when entangled particles are united by a single quantum state and therefore retain correlation at distance. For example, by measuring the state of one entangled photon, scientists can determine the state of the other one. Photons become ent…

• ITMO Fellowship Stories: 'I Always Come Back to Russia'

  …on transfer is impossible without its loss. To solve this problem one should divide a line into several parts and then equip them with quantum repeaters that provide entangled quantum state. Thus information transferring through these sections can be described using Bell's theorem. It is a complex method of data transfer, using which one has to save quantum state. According to quantum communication transmitter and receiver modules are usually called Alice and Bob respectively. For example, Alice and Bob determine a …
