A quantum computer has used a single atom to model the complex dynamics of organic molecules interacting with light ...

When a molecule absorbs light, it undergoes a whirlwind of quantum-mechanical transformations. Electrons jump between energy ...

Quantum computing, machines built on the counterintuitive laws of sub-atomic physics, promises raw processing muscle so immense it can crack today’s “unhackable” encryption in seconds.  The same ...

Every single atom will behave identically ... that we can perform the sort of complex operations that would lead quantum computers to have an advantage in useful calculations.

an antimony atom can store eight different values—"0," "1" and six other stops in between. This has profound consequences for error-proofing quantum computers, the team explained in its paper.

The most striking idea of this new field is to store information as a “quantum object” (most simply, either an atom, or a nano ... which result you get on a single try is unpredictable.

The work builds on the 2010 Nobel Prize–winning discovery that peeling carbon apart until it reaches a single layer of atoms creates a new two-dimensional (2D) material called graphene with special ...

In the past, such events were regarded as 'momentary' or 'instantaneous': An electron orbits the nucleus of an atom ... use quantum entanglement for quantum cryptography or quantum computers.

The single atom can encode the information that is normally spread across a dozen or so ‘qubits’, the computational units used in most quantum computers. The findings were published on 14 May ...
