• ITMO Scientists Propose Systems With Unique Interaction Between Photons and Mechanical Motion of Atoms

  … storing and processing quantum information.” One of the major problems in creating devices for storing and processing quantum information (quantum computers) is that quantum states are extremely fragile and should be isolated from the environment. Therefore, scientists are now challenged to figure out how to store quantum information so that it remains resi…

• ITMO Student Dmitriy Tsarev on Theoretical Physicists, Quantum Physics and Its Similarities With Professional Sports

  …measuring equipment have been overcome and measurements are carried out at the level of quantum noise. However, the measurement accuracy of any interferometer depends on which quantum state we use as a starting point.  The classic approach is to shine a conventional (coherent) laser light at the input of the device. This is a well-studied and reliable procedure bu…

• Is Fully Hack-Proof Code Possible?

  …um radiation, which offers a range of useful properties. Unlike powerful laser radiation used today in almost all data transmission systems, it’s impossible to copy an unknown quantum state, impossible to split it, and it self-disrupts when measured.    Read also: ITMO Researcher Represents Russia at QKD Security Workshop Is this the fabled unhackabl…

• Scientists from ITMO University Describe and Emulate New Quantum State of Entangled Photons

  …niversity physicists have accomplished.  “The main point of our work is not only the prediction of topological two-photon states, but also emulation of such multiparticle quantum states,” explains Nikita Olekhno. “A lot can be explained through analogy. For instance, when I tell school students about optical resonant nanoparticles, I compare them with acoustic r…

• Five ITMO University Scientists Awarded SRIE Scholarship

  …ectric field of a radiofrequency trap. In my research, I propose to cool the nanocrystal to temperatures close to zero, which coincides with its transition to a macroscopic quantum state. In this state, the nanocrystal starts to develop quantum properties. At the same time, it is too big to be an object of the microworld and too small for people to be able to see …

• Quantum Computing: Challenges, Prospects, and Current Developments

  …nt of elements in the system. At the same time, if we were to do it quantum-mechanically, the process would occur naturally. It should also be noted that, unlike classic bits, quantum states cannot be copied because an evolution operator is a unitary operator. In 1994, Peter Shor shown that quantum algorithms can find prime factors at an exponentially higher p…

  … necessary to teach them to correct their mistakes. However, what we can do with quantum computers is simulate quantum systems. Scientists have already managed to preserve the quantum state of numerous atoms or photons; with just a hundred of such particles, called qubits, it is possible to perform some really complex calculations. I believe that in five years physic…
