• A Novel Atom-Twisting Method Proposed by ITMO Researchers

  …e, interacts with an electron in a hydrogen-like atom. The experiment showed that an atom gains the twisted state of a photon when the latter is absorbed. “Given that the quantum state of light is a form of data, it should be preserved loss-free in case of any light-system interaction. We found that if this information cannot be transferred to an electron direct…

• ITMO’s Monday Science Roundup #52

  …Research Quantum states are something our news portal has written about at length – and for good reason. After all, it can be said that the future of quantum computers depends entirely on whether we can ensure the stability of these mathematical entities. Recently, a team at ITMO’s School of Physics and Engineering has produced a scientific paper describing the…

• Longer-Lived Quantum States Suggested at ITMO

  …rds quantum computers is spontaneous emission – the possibility of a qubit being destroyed at any moment by emitting into its environment. This phenomenon shortens the life of quantum states and essentially renders the recording of information impossible in quantum systems. Large atomic structures (containing dozens or hundreds of atoms) are typically used to suppres…

• Physicists From ITMO Generate Single Photons For Secure Information Encryption

  …ransmit and receive information via optical channels. With this method, data storage and transmission can be more secure: if a malefactor attempts to intercept the photon, its quantum state will change and the addressee will know that the system has been compromised.  However, single photons are not easy to acquire: currently, it can be done with the help of suppr…

• 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 …

  …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…

  …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…
