One of the most difficult problems with #QuantumComputing relates to increasing the size of the quantum computer. Researchers globally are seeking to solve this “challenge of scale.” To bring quantum scaling closer to reality, researchers from 14 institutions collaborated through the Co-design Center for Quantum Advantage (C2QA). Together, they constructed the ARQUIN framework — a pipeline to simulate large-scale distributed quantum computers as different layers. #C2QA #Quantum

While some embrace spooky season with carved pumpkins and ghoulish decorations, #quantum scientists dive headfirst into spooky quantum properties, called superposition and entanglement, all year long. #C2QA researchers are designing qubits (quantum computer building blocks) that retain information in a peculiar manner. Instead of existing as a 0 or 1, like classical bits, qubits can exist as 0, 1, or any combination of the two states. In other words, they can exist in a superposition of several states until they are measured. This property enables quantum computers to tackle complex calculations that can’t be solved with classical computers. Other quantum researchers from our lead institution, Brookhaven National Laboratory, are working on a quantum network that transmits entangled photos throughout Long Island, New York, and the New York City metropolitan area. But what does that mean? And how is it spooky? The researchers can generate pairs of entangled photons and transmit them in different directions. No matter how distant the photons are, they are still entangled, so taking a measurement of one photon can immediately reveal information about its pair. Quantum information science may be spooky, but it’s certainly not scary. Superposition and entanglement are key for storing and transmitting quantum information. And they enable secure communications and powerful computing capabilities that may revolutionize several industries, like scientific research, finance, weather forecasting, and healthcare. Happy Halloween! 🎃 👻

Quantum researchers have dedicated significant efforts to developing superconducting #qubits with a sandwich-like "SIS" junction (a), made up of two superconducting layers (Al) separated by an insulator (AlOX). These qubits perform well, but they're difficult to manufacture at the precision needed for the large-scale production of quantum computers. So, researchers from Brookhaven National Laboratory looked into a different superconducting qubit architecture that has a constriction junction (b), instead of an SIS junction. Constriction junctions, which lay flat and consist of two superconducting layers connected by a thin superconducting wire, can be manufactured more readily at scale. With a series of mathematical analyses, the researchers demonstrated that qubits with constriction junctions, when made with specific materials, perform comparably to qubits with SIS junctions. What's next for the #CFNatBrookhaven researchers? They are already exploring qubit materials that meet the guidelines outlined in their paper, which was recently published in Physical Review A, and they look forward to exploiting the benefits of the simpler qubit fabrication process.

A new framework for simulating a distributed #quantum computing system, known as ARQUIN, was developed by 14 of #C2QA's partner institutions. The framework was split into "layers," so each research group could specialize in a specific aspect of the project. For example, some researchers focused on optimizing microwave-to-optical transduction while others designed algorithms that were compatible with the distributed architecture. The completed framework, in which all the layers come together, marks an important step toward efficient and scalable quantum computation. The team included researchers from Pacific Northwest National Laboratory, Brookhaven National Laboratory, the Massachusetts Institute of Technology, Yale University, Princeton University, Virginia Tech, IBM Quantum, and more.
