China's quantum computing advances are prominently featured this week, with the launch of China's largest quantum cloud computing platform by China Mobile and China Electronics Technology Group Corp. This platform signifies China's shift towards practical quantum computing, offering public quantum cloud services and open quantum fusion computing power testing environments for researchers and enterprises. Google has introduced a new algorithm that enhances the security of the FIDO2 industry standard, that would be quantum safe. Unitary Fund's $1.5M grant from the National Science Foundation demonstrates the growing support for open-source quantum projects and the push to foster an inclusive quantum ecosystem. This is part of a wider $38M program from the NSF. And in the UK the government created a fund of £30M to develop quantum computer hardware testbeds highlights the international drive to benchmark quantum technology advancements. Gero works towards quantum for health and aging processesMeanwhile, advancements in quantum hardware continue with researchers from QuEra proposing a novel scheme to perform fault-tolerant quantum computation using high-rate quantum low-density parity-check codes. Why is this important?Quantum error correction (QEC) is believed to be essential for realizing large-scale fault-tolerant quantum information processing. However, traditional schemes for achieving quantum error correction, such as the paradigmatic surface code, are generally very costly in terms of resource overhead, requiring millions of qubits to solve problems of interest. qLDPC codes can significantly reduce the space overhead of fault-tolerant quantum computing, but the complex, long-range connectivity required can be hard to implement in near-term hardware. But what if you could move your qubits around? It turns out the way qubits are moved around in neutral atom quantum computers naturally matches the product structure of many qLDPC codes, enabling their hardware-efficient implementation. This can reduce the number of qubits needed to execute large-scale quantum computations by over an order of magnitude, bringing fault-tolerant quantum computing closer to reality.
