The rapid development of flexible and wearable electronics is giving rise to an exciting range of applications, from smart watches and flexible displays — such as smart phones, tablets, and TV — to smart fabrics, smart glass, transdermal patches, sensors, and more. With this rise, demand has increased for high-performance flexible batteries.
If a quantum processor is to run algorithms beyond the scope of classical simulations, a large number of qubits are required, along with low error rates on readout and logical operations, such as single and two-qubit gates.
By employing a technique called scanning tunnelling microscopy lithography, the scientists are able to directly measure each atom’s wavefunction, thereby determining its exact location in the chip. “We are the only group in the world who can actually see where our qubits are,”
Every Bristlecone chip features 72 qubits. The general assumption in the industry is that it will take 49 qubits to achieve quantum supremacy, but Google also cautions that a quantum computer isn’t just about qubits. “Operating a device such as Bristlecone at low system error requires harmony between a full stack of technology ranging from software and control electronics to the processor itself,” the team writes today.
