Zurich Instruments offers Quantum Computing researchers a fast track to unleashing the power of parametric amplification for qubit readout. While being critical to achieve the high measurement speed and low error rates needed for quantum error correction, parametric amplification often requires dedicated control electronics for microwave signal conditioning. With the new SHFPPC Parametric Pump Controller, […]
Quantum network nodes with warm atoms
Physicists at the University of Basel, Switzerland, have now developed a network node for quantum communication networks that can store single photons in a vapor cell and pass them on later. In quantum communication networks, information is transmitted by single particles of light (photons). At the nodes of such a network buffer elements are needed […]
Breakthrough in integrated photonics
Scientists at EPFL, Switzerland, have built a compact waveguide amplifier by successfully incorporating rare-earth ions into integrated photonic circuits. The device produces record output power compared to commercial fiber amplifiers, a first in the development of integrated photonics over the last decades. Erbium-doped fiber amplifiers (EDFAs) are devices that can provide gain to the optical […]
Covestro and QC Ware develop quantum algorithms for materials R&D
Covestro, one of the world’s leading polymer companies, and QC Ware have announced the signing of a five-year collaboration agreement. The objective of the collaboration is to help prepare Covestro to fully deploy quantum algorithms for the discovery of new materials and catalysts on near-term quantum hardware. The agreement is aligned with Covestro’s goal to enhance the company’s digital R&D processes to pave […]
Receiver-Device-Independent Quantum Key Distribution (QKD)
Researchers at University of Geneva (UNIGE) and CEA have presented new protocols for Quantum Key Distribution (QKD) in a prepare-and-measure setup with an asymmetric level of trust. While the device of the sender (Alice) is partially characterized, the receiver’s (Bob’s) device is treated as a black-box. The security of the protocols is based on the […]
Quantum one-way street in topological insulator nanowires
Scientists have demonstrated that wires more than 100 times thinner than a human hair can act like a quantum one-way street for electrons when made of a peculiar material known as a topological insulator. The discovery opens the pathway for new technological applications of devices made from topological insulators and demonstrates a significant step on […]
The side effects of quantum error correction and how to cope with them
It is well established that quantum error correction can improve the performance of quantum sensors. But new theory work cautions that, unexpectedly, the approach can also give rise to inaccurate and misleading results — and shows how to rectify these shortcomings. Quantum systems can interact with one another and with their surroundings in ways that […]
New world record for qubit storage
A UNIGE team in Geneva, Switzerland, has succeeded in storing a quantum bit for 20 milliseconds. A duration that had never before been achieved by a solid-state quantum memory. Long-duration quantum memories for photonic qubits are essential components for achieving long-distance quantum networks and repeaters. The mapping of optical states onto coherent spin-waves in rare […]
EPFL offers a new Master in Quantum Science and Engineering
This new program (Master’s in Quantum Science and Engineering) at EPFL, Lausanne, Switzerland, allows students with varied backgrounds in science and engineering to have the opportunity to acquire a comprehensive set of skills to become the main actors of the “quantum revolution” . Quantum science and technology is bringing a paradigm shift in the way […]
Antiprotons in superfluid: a new way for sensitive measurements of antimatter
A team of scientists at CERN led by MPQ physicist Masaki Hori has found that a hybrid antimatter-matter atom behaves in an unexpected way when submerged in superfluid helium. The result may open a new way for antimatter to be used to study the properties of condensed matter, or to search for antimatter in cosmic […]
