Researchers from Google and the University of California Santa Barbara have taken an important step towards the goal of building a large-scale quantum computer.
Writing in the journal Quantum Science and Technology, they present a new process for creating superconducting interconnects, which are compatible with existing superconducting qubit technology.
The race to develop the first large-scale error-corrected quantum computer is extremely competitive, and the process itself is complex. Whereas classical computers encode data into binary digits (bits) that exist in one of two states, a quantum computer stores information in quantum bits (qubits) that may be entangled with each other and placed in a superposition of both states simultaneously.

Scientists have expanded the building blocks of DNA to create a stable semi-synthetic organism that can produce biological compounds entirely new to nature.
The DNA that makes up essentially all living things on Earth consists of arrangements of four basic nucleotides, but the new life-form developed by researchers in the US makes use of six – and that’s where things get interesting.
The semi-synthetic organism (SSO) engineered by a team at the Scripps Research Institute in California is made from the same four regular nucleobases as you and I – adenine (A), cytosine ©, guanine (G), and thymine (T) – but it’s also got two unnatural nucleotides to call upon.
