Building single-atom qubits under a microscope

Our team at IBM Research made a breakthrough in controlling the quantum behavior of individual atoms, demonstrating a versatile new building block for quantum computation.

Quantum vacuum: Less than zero energy

Energy is a quantity that must always be positive—at least that's what our intuition tells us. If every single particle is removed from a certain volume until there is nothing left that could possibly carry energy, then ...

Entanglement sent over 50 km of optical fiber

The quantum internet promises absolutely tap-proof communication and powerful distributed sensor networks for new science and technology. However, because quantum information cannot be copied, it is not possible to send this ...

Novel networking

As a new joint appointee at the U.S. Department of Energy's Brookhaven National Laboratory, Eden Figueroa is getting accustomed to traversing between his roles within the Lab's Computational Science Initiative (CSI) and Instrumentation ...
