Hybrid qubits solve key hurdle to quantum computing

Spin-based quantum computers have the potential to tackle difficult mathematical problems that cannot be solved using ordinary computers, but many problems remain in making these machines scalable. Now, an international group ...

Quantum Maxwell's demon 'teleports' entropy out of a qubit

Researchers from the Moscow Institute of Physics and Technology, ETH Zurich, and Argonne National Laboratory, U.S, have described an extended quantum Maxwell's demon, a device locally violating the second law of thermodynamics ...

Error correction in the quantum world

Sebastian Krinner is the first winner of the Lopez-Loreta Prize at ETH Zurich. The physicist has a clear goal: he wants to build a quantum computer that is not only powerful, but also works without errors.

One step closer to complex quantum teleportation

The experimental mastery of complex quantum systems is required for future technologies like quantum computers and quantum encryption. Scientists from the University of Vienna and the Austrian Academy of Sciences have broken ...

Tests show integrated quantum chip operations possible

Quantum computers that are capable of solving complex problems, like drug design or machine learning, will require millions of quantum bits—or qubits—connected in an integrated way and designed to correct errors that ...
