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.

Using 2D Layered Materials to Develop Powerful Quantum Light Sources

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 Technique Helps Elucidate Role of Phonons in Copper-Based Superconductivity

Since the 1980s, scientists have been well aware of high-temperature superconducting copper-based materials, or cuprates. Below a specific temperature (roughly -130°C), electrical resistance disappears from these materials and magnetic flux fields are released. However, the reason for that superconductivity continues to be discussed and investigated.

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.

Physicists Manipulate Magnetism with Light

With the help of a “playground” they created for observing exotic physics, MIT scientists and colleagues have not only found a new way to manipulate magnetism in a material with light but have also realized a rare form of matter. The former could lead to applications including computer memory storage devices that can read or write information in a much faster way, while the latter introduces new physics.

Astronomers Spot Unusual Object Unlike Anything Ever Seen Before

While mapping the universe for radio waves, researchers discovered a rare entity that discharges a massive burst of energy three times per hour, and it is unlike anything astronomers have ever observed.

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.

Controlling Quantum-Mechanical Entanglement in Attosecond Pump-Probe Experiments

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 Find Rare Kondo Effect in Transition Metal Oxide

As temperature decreases, so does the electrical resistance of metals -; most of the time. In metal with magnetic impurities, electrical resistance can increase as the temperature drops due to a strange phenomenon called the Kondo effect.

New Qubits Could Make a Promising Foundation for Quantum Computers

MIT physicists have discovered a new quantum bit, or "qubit," in the form of vibrating pairs of atoms known as fermions.

Physicist Proposes a Radical Solution to Century Old Problem of Radiation Reaction

A Lancaster physicist has proposed a radical solution to the question of how a charged particle, such as an electron, responded to its own electromagnetic field.

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.

Research Reveals Rare Quantum-Like Behavior of Confined Water

Recently, "National Science Review" published online the latest research results of the research team of Professor Zhuhua Zhang and Prof. Wanlin Guo from Institute for Frontier Science, Nanjing University of Aeronautics and Astronautics. The phenomenon of quantum-like Friedel oscillations in one-dimensional confined water was reported.

Creating Matter Directly from Collisions of Light

Nuclear scientists have used a powerful particle accelerator to create matter directly from collisions of light. Scientists predicted this process in the 1930s, but it has never been achieved in a single direct step. The researchers accelerated two beams of gold ions to close to the speed of light in opposite directions.
