We demonstrate a Josephson parametric amplifier design with a band-pass impedance matching network based on a third-order Chebyshev prototype. We measured eight amplifiers operating at 4.6~GHz that exhibit gains of 20~dB with less than 1~dB gain ripple and up to 500~MHz bandwidth. The amplifiers further achieve high input saturation powers around $-93$~dBm based on the use of rf-SQUID arrays as… We we need to pass each qubit separately through a Hadamard gate, then take their tensor product. Today, many firms attempt to make genuine quantum hardware available to thousands of developers, a tool that scientists only began to conceive three… Read More

Strong cryptography is vital to overall individual and societal cybersecurity. It provides the foundation for secure transmission and data storage, and for authenticating trusted connections between people and systems. Another alternative to public-key cryptography for key exchange is quantum key-distribution. Here, quantum methods are used by the sender and receiver to establish a symmetric key. If these encryption methods are broken, people will not be able to trust the data they transmit or receive over the internet, even if it is encrypted. Adversaries will be able to create bogus certificates, calling into question the validity of any digital identity online.… Read More

Bluntly, if they don’t explain the actual underlying mathematical model, then you could spend years watching and rewatching such videos, and you’d never really get it. It’s like hanging out with a group of basketball players and listening to them talk about basketball. But unless you actually spend a lot of time playing, you’re never going to learn to play basketball. To understand quantum computing, you absolutely must become fluent in the mathematical model. “The blurred line between industry and national security in China gives them an advantage,” says David Spirk, former chief data officer at the Department of Defense.… Read More

In pursuing the standard improvement, IJPH has published articles twice a 12 months since 2017. Since 2020, this journal is published frequently three times a year, in April, August and December. Quadripartite organizations , a complete One Health Joint Plan of Action is in improvement, supported and suggested by the One Health High-Level Expert Panel. Garmin Cycling Coach helps build personalised plans that adapt primarily based on performance and restoration. These plans also let cyclists see how their present abilities will stack up towards the calls for of the course they plan on riding—including elevation acquire and distance requirements. Cyclists… Read More
