EUR 16 Million Funding 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.

Developing Quantum Photonics Technologies Based on 2D Materials

Due to their unique properties, 2D materials, which consist of a single layer of atoms, are increasingly being used in optoelectronic devices, as quantum light sources and in integrated circuits. Research into the quantum technologies enabled by 2D materials has been advancing rapidly since 2015, with further potential for yet further advances.

New Approach Moves Trapped Ion Pairs Through a Laser Beam to Create Entangled Gates

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. Now, scientists at the Georgia Tech Research Institute (GTRI) have demonstrated the feasibility of a new approach that moves trapped ion pairs through a single laser beam, potentially reducing power requirements and simplifying the system.

Quantum-Mechanical Entanglement Takes Center Stage at Attosecond Laser Laboratory

Quantum mechanics is famous for the way that its predictions challenge intuitive human thinking developed through the way that we experience the everyday world around us. Among other things, quantum objects can display both particle- and wave-like character, can interfere and can occur in the form of quantum superpositions.

Researchers Build an Ultrafast Quantum Battery

Quantum batteries are a new class of energy storage devices that operate according to the principles of quantum physics, the science that studies the infinitely small where the laws of classical physics do not always apply.

Spin Qubits can be Potentially Useful for Quantum Networks that Employ Optical Fibers

Quantum computers may be able to solve science problems that are impossible for today's fastest conventional supercomputers. Quantum sensors may be able to measure signals that cannot be measured by today's most sensitive sensors. Quantum bits (qubits) are the building blocks for these devices.

Experimental Realization of Atom-Optically Synthetic Gauge Field for a Noninteracting Bose Gas

Gauge fields describe the basic interactions between charged particles and are responsible for various emergent topological phases of matter. This concept recently has been further generalized to charge neutral systems by engineering an analog Hamiltonian that governs the effective dynamics of neutral particles subject to magnetic fields.

Novel Technique to Simulate Light-Matter Interactions at the Atomic Scale

Light–matter interactions form the basis of many important technologies, including lasers, light-emitting diodes (LEDs), and atomic clocks. However, usual computational approaches for modeling such interactions have limited usefulness and capability. Now, researchers from Japan have developed a technique that overcomes these limitations.
