PhotonQ Project Receives EUR 16 Million to Develop a Photonic Quantum Processor

Quantum computers will one day be able to solve problems at high speed that cannot be handled by classical computer systems. However, in order for these computers to become practical, they must process a significantly higher number of qubits and have lower error rates. A research project led by Professor Stefanie Barz from the University of Stuttgart is now developing a photonic quantum processor for this purpose.

Robust and Low-Cost Cryptosystem can Withstand Attacks from Large-Scale Quantum Computers

While for most of us cryptographic systems are things that just run "under the hood," they are an essential element in the world of digital communications.

Long-Term Research Grant to Develop Carbon Nanomaterials for Futuristic Quantum Technologies

After 12 years of hard work, scientists at Empa have managed to develop novel carbon materials with surprising, hitherto impossible magnetic and electronic properties, which could be used to construct quantum computers with unique architectures in the future.

Researchers Propose a New Architecture for Scalable Quantum Computers

Physicists from the University of Amsterdam have proposed a new architecture for a scalable quantum computer. Making use of the collective motion of the constituent particles, they were able to construct new building blocks for quantum computing that pose fewer technical difficulties than current state-of-the art methods. The results were recently published in Physical Review Letters.

GTRI Study Creates a Transport-Enabled Entangling Gate with Two Trapped Ions

Trapped ions excited with a laser beam can be used to create entangled qubits in quantum information systems, but addressing several stationary pairs of ions in a trap requires multiple optical switches and complex controls.

Using Tiny Materials to Build Superconducting Qubits may Lead to Better, Smaller Quantum Devices

Like the transistors in a classical computer, superconducting qubits are the building blocks of a quantum computer. While engineers have been able to shrink transistors to nanometer scales, however, superconducting qubits are still measured in millimeters. This is one reason a practical quantum computing device couldn't be miniaturized to the size of a smartphone, for instance.

New Tool can Determine How Big a Quantum Computer Needs to Be for Solving Problems

Quantum computers are expected to be disruptive and potentially impact many industry sectors. So researchers in the United Kingdom and the Netherlands decided to explore two very different quantum problems: breaking the encryption of Bitcoin (a digital currency) and simulating the molecule responsible for biological nitrogen fixation.

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.
