Quantum Computing Companies
IBM
IBM has laid out one of the most detailed and aggressive quantum computing roadmaps in the industry. Over the past few years, IBM Quantum has consistently hit its interim milestones, expanding both the scale of its processors and the sophistication of its approach to quantum computing. As a long-time pioneer in quantum computing, IBM was the first to put real quantum hardware on the cloud…

Quantum Computing Companies
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.…

Diraq
Diraq is an Australian quantum computing startup (founded in 2022 as a spin-off from UNSW Sydney by Professor Andrew Dzurak) focused on building large-scale quantum processors based on silicon-based spin qubits. The company’s strategy is to leverage standard silicon CMOS manufacturing - using modified transistor structures that act as quantum bits - to achieve practical and scalable quantum computing. Diraq’s qubits are single-electron spins confined…

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…

Amazon AWS
Amazon has taken a dual approach to quantum computing, combining cutting-edge hardware research with commercial cloud services. On the R&D side, Amazon Web Services (AWS) established the AWS Center for Quantum Computing at Caltech in 2019, explicitly aiming to build a fault-tolerant quantum computer capable of solving problems beyond classical reach. This effort focuses on superconducting qubits and novel error-correction techniques, leveraging a team of…

Alice & Bob
Alice & Bob is a Paris-based quantum computing startup (founded in Feb 2020 by Dr. Théau Peronnin and Dr. Raphaël Lescanne) focused on building a universal, fault-tolerant quantum computer using a novel “cat qubit” architecture. The company’s approach leverages superconducting cat qubits, quantum bits that are inherently protected from certain errors, to drastically reduce the overhead for error correction. Backed by substantial funding and scientific…
