Diamond quantum memory with Germanium vacancy exceeds coherence time of 20 ms
Precision in Quantum Network Operations: Laser beams finely tuned for resonant addressing and readout illuminate the GeV quantum memory. Credit: Katharina Senkalla. The color centers of diamond are the focus…
Scientists report first look at electrons moving in real-time in liquid water
Scientists used a synchronized attosecond X-ray pulse pair (pictured pink and green here) from an X-ray free electron laser to study the energetic response of electrons (gold) in liquid water…
A new design for quantum computers
Illustration of a quantum simulator with atoms trapped into a square lattice with lasers. The small spheres at the corners are atoms in their lowest energy state. The ones inside…
