(Original title: Intel delivers 49-qubit test chip: computing power is equal to 5,000 8th generation i7).
CEO Brian Krzanich announced today in a CES presentation that Intel has successfully designed, manufactured and delivered a 49-qubit (qubit) superconducting test chip, just three months after Intel delivered a 17-qubit chip last October.

The 49-qubit chip, codenamed Tangle Lake, is considered a milestone by Intel. Because at such a scale, researchers have been allowed to evaluate and improve error correction techniques and simulation calculations.
When it comes to the commercial use of quantum computing, Mike Mayberry, vice president of Intel and head of Intel Labs, said that it will take another 5 to 7 years.
7-bit, 17-bit, 49-bit quantum chips.
In addition to superconducting qubits, Intel has also built a 1-qubit spin chip based on a 300mm process. The size and unit area of a self-selected qubit is more impressive than that of a superconducting qubit, and it is like a single-electron transistor.
Previously, IBM announced that it had completed a 50-qubit computer, and this time it made a big ......show at CES
PS: Many people may not know about qubits, and they are even more confused about quantum computers.
Traditional computers are binary, that is, they can only use "0" and "1" to record all the information states, and each step can only do 2 times - 2 times the operation.
A quantum computer with 2 qubits can do 2 to the 2nd power in each step - that is, 4 operations, so Intel's chip can reach 2 to the 49th power in one step, which is 562 trillion times (at present, the world's strongest supercomputing Shenwei Taihu Light is 9 per second.)300 million times, i7-8700K about 110 billion times).
It is reported that China has independently developed a 10-qubit superconducting quantum circuit sample.
