• ITMO Scientists Increase Sensitivity of Levitating Particle Sensors

  …es are literally levitating. Researchers use this method to precisely measure the force, torque, and acceleration, as well as to study the fundamental laws of physics, such as quantum states and nonlinear processes. As this method excludes external noise and unwanted influences on an object, it increases the system’s sensitivity. In other words, a nano- or micropa…

• Maglev Trains, Smartphones, and Biochips: Biggest Breakthroughs in Quantum Mechanics

  …include light quanta (photons), we can feel and see everything that surrounds us. However, no two identical fermions can occupy the same space position while being in the same quantum state – they will start to repel one another; but this does not apply to bosons. This pattern, which was first described by Austrian physicist Wolfgang Pauli, grew to become a fundament…

• ITMO’s Monday Science Roundup #83

  … counterparts, quantum computers are facing an issue when it comes to increasing capacities. In their case, it has to do with the speed of data transfer – or, more accurately, quantum state transfer.  Now, scientists from ITMO University and the London Institute for Mathematical Sciences have suggested a better way to transfer states from qubit to qubit. Using a c…

• Time-Optimal Transfer of Quantum State Achieved by ITMO Physicists

  …ithin the constraints of quantum physics, allowing for the excitation to travel from the first qubit in the chain to the last, safe and sound.  “The method we propose for quantum state transfer relies on precise control of system parameters. Hence, if there’s noise, the accuracy of the transfer decreases. Nevertheless, other methods also display performance loss…

• 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 …
