A newly discovered prime number makes its debut

On December 26, 2017, J. Pace, G. Woltman, S. Kurowski, A. Blosser, and their co-authors announced the discovery of a new prime number: 2⁷⁷²³²⁹¹⁷-1. It's an excellent opportunity to take a small tour through the ...

Quantum race accelerates development of silicon quantum chip

A team of TU Delft scientists led by Professor Vandersypen seeks to create better and more reliable quantum processors. In a neck-and-neck race with competitors, they showed that quantum information of an electron spin can ...

Physicists create quantum state detector

Physicists from MIPT have teamed up with their colleagues in Russia and Great Britain and developed a superconducting quantum state detector. The new device can detect magnetic fields at low temperatures and is useful to ...

Random numbers—hard times ahead for hackers

Whenever we need to communicate in secret, a cryptographic key is needed. For this key to work, it must consist of numbers chosen at random without any structure – just the opposite of using the birthdate of our favourite ...

Quantum physics offers new way to factor numbers

(Phys.org)—Any number can, in theory, be written as the product of prime numbers. For small numbers, this is easy (for example, the prime factors of 12 are 2, 2, and 3), but for large numbers, prime factorization becomes ...
