TOP NEWS & RESEARCH

NEWS

QUANTUM COMPUTING IS GOING DEEP UNDERGROUND

The Brief Byte: Researchers from the University of Waterloo and the Chalmers University of Technology are partnering with the cosmic radiation experts at SNOLAB in a cross-disciplinary effort to understand more about the effect of radiation on decoherence in qubits.

Highlights:

1. Sponsored by the US Army Research Office, the “Advanced Characterization and Mitigation of Qubit Decoherence in a Deep Underground Environment” grant will allow researchers the space and time they need to further explore the link between cosmic rays and qubits.

2. We’ve recently identified that cosmic radiation has been one source of noise in NISQ devices; a qubit hit by a high energy particle will result in the propagation of quantum error to neighboring qubits.

3. The purported lowest muon flux in the world of SNOLAB along with the Canadian Shield that shields high energy particles from space makes this facility the ideal environment to isolate noise from radiation effects.

RESEARCH

PHOTON TRIPLET SPEEDS UP QUANTUM NETWORK

The Brief Byte: Viktor Krutyanskiy and his team at the University of Innsbruck have significantly increased the transmission rate of quantum information by successfully sending groups of three entangled photons through a 101-km optical fiber, more than doubling the previous success rates of single-photon transfers.

Highlights:

1. They used an optical cavity to trap calcium ions capable of emitting a photon entangled with the ion. This was essential for maintaining quantum network connections over long distances.

2. The team achieved a new success rate of 2.9 entangled photons per second across a fiber link extending 101 kilometers. The previously recorded rate was 1.2 per second with the single-ion method.

RESEARCH

OVERVIEW OF “LAYERED UPLOADING FOR QUANTUM CONVOLUTIONAL NEURAL NETWORKS”

The Brief Byte: Researchers are investigating the potential of QCNNs in malware detection with new architecture proposal where data is uploaded along the length of a quantum circuit versus adding additional qubits to handle the data.

Highlights:

1. The new QCNN architecture is evaluated against standard models using two datasets: the MNIST for image classification and a malware-specific dataset consisting of benign and malicious PE file images.

2. One of the benefits of the new QCNN architecture is that it allows for effective information utilization in scenarios with limited data and computational resources.

3. Ultimately, the architecture encodes more features per layer without enlarging the quantum circuit, showing improved performance in classification tasks over traditional QCNNs.

MORE BRIEF BYTES

• An interview with Mauro Paternostro, quantum physicist and new editor in chief of the Quantum Science and Technology journal

• A 59 page (!!!) overview on quantum thermodynamics as it relates to quantum technologies — I did not have the time to read 59 pages this morning for the research feature, BUT this is good stuff and I highly recommend taking a look at it

• Not quantum computing, but pretty cool quantum — giant quantum vortex experiment shown to resemble qualities of black holes, giving researchers a novel glimpse into the possible physics of these structures

• Researchers find that amorphous superconducting films of indium oxide exhibit a first-order quantum phase transition

CODE TIP

VARIATIONAL LSE SOLVER LIBRARY

Researchers have developed a user-friendly “variational-lse-solver” framework which builds off of and enhances existing approaches. The framework is designed for those developing end-to-end applications.
