#quantumcomputing 💡 A team from Aalto University has managed to measure qubits by using bolometers, instead of parametric amplifiers. This method enables single-shot qubit readout with minimal quantum noise, and consumes significantly less power than traditional amplifiers. Such an innovation could greatly enhance the scalability of quantum computers by reducing the size and energy consumption of the measurement process. Reference: András M.

A few years ago, some energy analysts began saying that "the past was about molecules, while the future is about electrons". This remains debatable. Yet in communications/computing, you might be more justified to say "the past was about electrons, while the future is about photons" ?! Today's 17-page note outlines the theory behind this second statement, going back to first principles, explaining why laser photonics can unlock 10x - 1Mx improvements in performance, bandwidth and efficiency. This matters for AI energy use, demand for copper vs fiber, and could yield a boom in the $400bn pa photonics industry (companies on page 17). At the cutting edge, lab-scale optical computers have achieved compute densities and efficiencies 100x better than NVIDIA GPUs (see page 14).

Shining Light on Quantum Magnets! Scientists just made a big leap in quantum tech by using light to visualize and control magnetic domains in antiferromagnets. These special materials could be the key to next-gen electronics and memory devices. What makes this cool? Real-time visualization: They used light to see how magnetic regions behave. Electric control: They even manipulated these regions with electric fields. This breakthrough could revolutionize how we use quantum materials in future tech. #QuantumTech #NextGenElectronics #Innovation #Antiferromagnets #QuantumMaterials

Bi2S3 is an exciting material due to its combination of semiconducting, optoelectronic, and thermoelectric properties, as well as its potential for the development of next-generation devices. Bi2S3 may be insulating in its bulk but host conducting states on its surface. This has increased interest in it for quantum computing and spintronics applications.

New Diamond Bonding Technique..... New developments are happening in quantum technology with a breakthrough in diamond bonding techniques, led by researchers from the University of Chicago. They’ve developed a method to bond diamonds directly with materials like silicon and lithium niobate, which opens the door to creating advanced quantum and conventional electronic devices. Previously, diamonds despite their thermal conductivity and chemical stability could only bond well with other diamonds, making their integration into electronic devices challenging and costly. With this new bonding technique allows for the use of ultra-thin diamond membranes (as thin as 100 nanometres) in electronics, maintaining all of diamond's properties. This step forward is great for quantum computing and sensors, as diamonds with nitrogen-vacancy centres are perfect for quantum applications. The technique could lead to more practical and scalable quantum devices, potentially revolutionizing industries from quantum sensing to everyday electronics like phones and computers.....
