Willow is a small chip for Google but a quantum leap for computing

Google recently unveiled its latest quantum processor, named ‘Willow’. This exponential growth in the information required to represent qubits’ states and the superposition of states are the major reasons why quantum computers could be more efficient and powerful than classical computers. Like a classical computer, a quantum computer is also a collection of qubits and a host of physical operations called quantum gates that change the states of qubits to perform calculations. The error rate According to Google, its new quantum processor Willow has significantly better error correction and is thus significantly faster than other quantum computers, not to mention classical computers as well. The next milestone for researchers to achieve is to lower the error rate — calculated as the ratio of the number of qubit errors to the number of gate operations — as they build ever-larger quantum computers with more physical qubits and more error correction operations.
