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 levels, atoms vibrate, and chemical bonds shift—all within millionths of a ...

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 ...

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.

Quantum computing company Pasqal has teamed up with Google Cloud to make its neutral atom quantum processing unit (QPU) available through the Google Cloud Marketplace. Customers using Google Cloud ...

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.

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 ...

Errors in quantum computers are an obstacle for their widespread use. But a team of scientists say that, by using an antimony atom and the Schrödinger's Cat thought experiment, they could have ...

Neutral-atom quantum computers offer significant advantages ... However, the number of quantum bits (qubits) that can be controlled in a single system is physically limited by constraints such ...

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 ...
