Quantum Science and Engineering encompass a broad and interdisciplinary field that explores the principles of quantum mechanics and applies them to various technologies and applications. Quantum mechanics is a fundamental theory in physics that describes the behavior of matter and energy at the smallest scales, such as atoms and subatomic particles. Quantum science and engineering leverage the unique properties of quantum systems to develop new technologies that can outperform classical systems in certain tasks.
Key aspects of Quantum Science and Engineering include:
The field of quantum science and engineering is rapidly evolving, and research in this area has the potential to revolutionize various industries, from information technology and cryptography to healthcare and materials science. Governments, academic institutions, and private companies worldwide are investing heavily in quantum research and development to unlock the full potential of quantum technologies.
‘Qumodes’ for quantum computing
"Physicists have demonstrated an alternative to qubits for quantum computers: qumodes. Qubits have properties that can only have two states when measured — for example, an electron with a spin that is in one direction or another. Qmodes’ properties can vary along a continuum — in this case, the brightness of a light pulse. To create qumodes, researchers carefully modified laser pulses by removing one photon at a time and creating interference between pairs of pulses. They then demonstrated that the resulting pulses had the properties that would be required, both to perform ‘digital’ quantum computations and to correct errors in those computations. In theory, qumodes could lead to faster and less error-prone quantum computers..."
