Wide bandwidth radio transmitters commonly use analog quadrature modulators (AQMs) to convert complex (I + j*Q) baseband signals to radio frequencies (RF). An AQM consists of a local oscillator (LO) ...

Today’s quantum computing hardware is severely limited in what it can do by errors that are difficult to avoid. There can be problems with everything from setting the initial state of a qubit to ...

These novel error-correction codes can handle quantum codes with hundreds of thousands of qubits, potentially enabling large-scale fault-tolerant quantum computing, with applications in diverse fields ...

Scientists have designed a physical qubit that behaves as an error-correcting "logical qubit," and now they think they can scale it up to make a useful quantum computer using a few hundred. When you ...

Quantum is smart. The progression toward embryonic quantum computing services represents a shift (you know what kind) in terms of the amount of intelligence we can apply to computing, data analytics ...

This “single-error-correct, double-error-detect” approach is often abbreviated SECDED. The second generation of ECC can correct a whole device, while the third adds internal ECC. In memory, the ...

To wrap up our recent series of articles on VESA video compression codecs, this month we will look at the use of video compression on digital display interfaces, using the DisplayPort 1.4 standard as ...

The current generation of quantum hardware has been termed “NISQ”: noisy, intermediate-scale quantum processors. “Intermediate-scale” refers to a qubit count that is typically in the dozens, while ...

UC Santa Barbara computer science assistant professor Murphy Yuezhen Niu, who is also a physicist, has been awarded a prestigious CAREER Award from the National Science Foundation to support her work ...

Quantum error correction can protect fragile captured starlight from being degraded by unwanted interactions with its environment. (Courtesy: iStock/angelinast) Space ...
