Researchers have successfully extended the quantum phase difference estimation algorithm, a general quantum algorithm for the direct calculations of energy gaps, to enable the direct calculation of ...

Two theoreticians from the National Institute of Standards and Technology (NIST) and Indiana University (IU) have published the most accurate values yet for fundamental atomic properties of a molecule ...

Conventional computers use bits, represented by zeros and ones, to transmit information, whereas quantum computers use quantum bits (qubits) instead. Similar to bits, qubits have two main states or ...

Sept. 2 (UPI) --Scientists in Japan have developed a new way to measure the energy difference of an atom and a molecule. The new algorithm, described Thursday in the journal Physical Chemistry ...

Disaster arrival into a queueing system causes all customers to leave the system instantaneously. We present a numerically stable algorithm for calculating the stationary state distribution of an ...

Although not a household scientific name like Albert Einstein or Isaac Newton, Indian mathematician Srinivasa Ramanujan—who tragically died in 1920 at the age of 32—was one of the greatest minds in ...

In recent years, research and development on quantum computers has made considerable progress. Quantum chemical calculations for electronic structures of atoms and molecules are attracting great ...
