Is Google’s Willow really a ‘wow’ moment for quantum computers?

Live Mint  

“Introducing Willow, our new state-of-the-art quantum-computing chip with a breakthrough that can reduce errors exponentially as we scale up using more qubits, cracking a 30-year challenge in the field," Alphabet CEO Sundar Pichai wrote in an X post on 9 December. Unlike conventional computers that use binary digits, quantum computers use ‘qubits’ and are therefore that much more powerful. According …

Mint Primer | Google’s Willow: Quantum computing’s next big leap?

Live Mint  

Two normal computer bits can exist in four possible states—00, 01, 10, or 11. A quantum computer allows two quantum bits to represent the four states at the same time due to ‘superposition’ and ‘entanglement’ properties, akin to running four computers. A quantum computer’s power grows exponentially with more qubits but it also induces errors, making the system like a …

Willow: What Google’s error-correcting chip means for quantum computing

Hindustan Times  

Google has just announced a new quantum chip, Willow, and the breakthrough needs to be read right in order to understand its implications. The idea is to incorporate error correction codes in “logical qubits”, each created across a number of “physical qubits”. Logical qubits make quantum computing even more complex since they are built across a number of physical qubits. …
