• Quantum Physics Is Everywhere: FAQ With ITMO Quantum Physicist

  …at we come up with the technologies themselves – not necessarily their applied forms. One of our projects is to use quantum entanglement to produce single particles in special quantum states. Essentially, this means that we are shaping a wave of particles – a simple visualization would be to imagine traces left by boats on water: they change the shape of the already …

• ITMO Researchers Twist Particles Using Quantum Entanglement

  …tum system, even if they are brought apart on a macroscopic scale. In this project, the researchers theoretically demonstrated that this property can be used to create twisted quantum states.  Normally, researchers would have to very precisely measure a particle’s properties, such as its mass or charge, but the new method places a great emphasis on the so-called g…

• Nobel Prize in Physics 2022: What Are Entangled Photons and Why They Are Important?

  …field soon? Why did the Nobel Committee focus on quantum information science this year?   What is quantum entanglement?   It is a phenomenon that occurs when quantum states of several particles become connected despite the space between them. Quantum entanglement, like other quantum features, is different from the properties of other objects in the …

• ITMO Scientists Design a Model to Protect Quantum Computing From Disorder

  …he impact of disorder in the system on corner states. They simulated a real structure with slightly different parameters of qubits and proved the topological protection of the quantum state: “By observing the changes in the system’s spectrum, we prove that topological corner states are protected from fluctuations in the couplings between qubits,” says Mark Lyuba…

• Dark Matter and Quantum States: All About ITMO's New Frontier Labs

  …erials in folded structures, which are monoatomic layers of two-dimensional semiconductors. Expected results Our goal is to demonstrate that it’s possible to control quantum states of substances optically. This has actually already been implemented in cold atom gratings: atoms are cooled down to mere thousandths of a degree above absolute zero, placed in an…

• 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…
