Intel
Intel’s quantum computing program has carved a distinctive path, marrying cutting-edge quantum research with the might of advanced silicon manufacturing. Over the past several years, Intel progressed from superconducting qubit test chips (17 and 49 qubits) to a focus on silicon spin qubits, culminating in the 12-qubit Tunnel Falls chip in 2023. Alongside qubit chips, Intel engineered a unique cryo-control architecture: the Horse Ridge I/II…

Google
Google is a frontrunner in the quest to build practical quantum computers. The company made headlines in 2019 by achieving quantum supremacy – using its 53-qubit Sycamore processor to perform in about 200 seconds a task that was estimated to require 10,000 years on a top supercomputer. This dramatic demonstration marked a milestone in computing and signaled Google’s emergence as a leader in quantum hardware.…

D-Wave Systems
D-Wave Systems is a pioneer in quantum computing known for its unique focus on quantum annealing - a specialized analog approach distinct from the gate-based quantum processors pursued by most competitors. Founded in 1999, D-Wave became the first company to commercially sell a quantum computer in 2011 with a 128-qubit annealing-based system. Rather than the circuit model of quantum computation (employing logic gates on qubits),…

Atom Computing
Atom Computing is a fast-rising startup developing gate-based quantum computers using optically trapped neutral atoms as qubits. The company made headlines in late 2023 by announcing a 1,225-site optical atom array populated with 1,180 qubits - the first universal quantum platform to surpass 1,000 qubits. This dramatic leap (from a ~100-qubit first-generation system to >1,000 qubits in one generation) showcases the inherent scalability of Atom’s…
