Quantum computing in 2024 has made significant progress in scalability. MIT leads with over 4,000 qubits, Atom Computing developed a 1,180-qubit platform, and IBM introduced a 1,121-qubit processor. These advancements are driving the industry closer to practical quantum systems.

Researchers at the University of Cologne advanced topological quantum computing by inducing error-resistant "flying qubits," potentially reducing noise and decoherence for more reliable quantum systems.

Companies offer “Quantum Computing as a Service” (QCaaS), raising security concerns. Oxford University's "blind quantum computing," published in Physical Review Letters, ensures secure, private computations using fiber networks and photon-detecting devices, promising advancements in various sectors.

MIT's QSoC using diamond color centers advances quantum computing with improved scalability, coherence, and control, surpassing traditional silicon-based qubits and bringing us closer to practical applications.

Researchers at Technische Universität Darmstadt developed "quantum bit supercharging," creating a 1,305 single-atom qubit array. This breakthrough enhances computational power and accelerates quantum research, marking a significant step toward scalable quantum computing.
