Vibrating atoms make robust qubits, physicists find

MIT physicists have discovered a new quantum bit, or “qubit,” in the form of vibrating pairs of atoms known as fermions. They found that when pairs of fermions are chilled and trapped in an optical lattice, the particles can exist simultaneously in two states — a weird quantum phenomenon known as superposition. In this case, the atoms held a superposition of two vibrational states, in which the pair wobbled against each other while also swinging in sync, at the same time.

The team was able to maintain this state of superposition among hundreds of vibrating pairs of fermions. In so doing, they achieved a new “quantum register,” or system of qubits, that appears to be robust over relatively long periods of time. The discovery, published today in the journal Nature, demonstrates that such wobbly qubits could be a promising foundation for future quantum computers.

Bose polarons meet their fate at quantum criticality

An electron moving through the crystal lattice of a solid slightly attracts the ions on its path. The electron and the crystal deformations move together a “quasi-particle”, heavier than the bare electron – the so-called polaron. Such quasi-particles form the basis of descriptions of many solids. However, in modern materials, such as the high-temperature superconducting cuprates,...

Squeezing space in a rotating quantum gas

In its most famous form, the Heisenberg uncertainty relation tells us that we cannot know both the position and momentum of a particle. The best we can do is to redistribute the intrinsic quantum uncertainty, for example by making position more precise at the expense of momentum, via a procedure known as squeezing. However, the...

Spin Transport in a Mott Insulator of Ultracold Fermions

Superconductivity is a phenomenon in materials whereby electron pairs can flow freely without resistance. As a consequence, no energy is lost while electrical current passes through the superconductor. The benefits, therefore, of superconducting materials which operate at room temperature are countless, and range from revolutionizing the electrical power transmission industry, to providing sweeping improvements in...

Ultracold molecules hold promise for quantum computing

Researchers have taken an important step toward the long-sought goal of a quantum computer, which in theory should be capable of vastly faster computations than conventional computers, for certain kinds of problems. The new work shows that collections of ultracold molecules can retain the information stored in them, for hundreds of times longer than researchers have previously achieved in these materials.
