[size=14.6667px]An interesting article regarding the quantum control of quantum computers and what it all means can be found here.American startup EeroQ came out of stealth mode and introduced a quantum processor called Wonder Lake. It is not yet a functional processor or prototype, but a design of it, which is currently going into production. As such, qubits will use electrons (ie spin) located on liquid helium. Apart from helium, the rest of the chip will be manufactured using CMOS technology. The chip should handle up to  qubits with just  control lines – that's pretty decent.

[size=14.6667px]The approach Chinese American Phone Number List[size=14.6667px] is to make a lot of qubits and then improve them, others do the opposite. Simulations predict that the coherence time is >  seconds, . percent fidelity of quantum operations, high connectivity, etc. A very respectable list. When they get the CMOS part from the manufacturer, fill it with helium and start testing, we'll see how it goes, hopefully well. They have been working on this architecture for  ones working on this approach.

[size=14.6667px]Quantum algorithms and softwareIBM has published an interesting post on its blog regarding the possible acceleration of the Metropolis-Hastings algorithm on quantum computers. The Metropolis-Hastings algorithm is a type of Monte Carlo algorithm for obtaining a sequence of random samples from a probability distribution for which direct sampling is difficult. It is used in statistics or physics, for example for numerical integration.Google Quantum AI has released a new version of its quantum framework Cirq .
