International Business Machines Corp. IBM, Alphabet Inc.‘s GOOGL GOOG Google, Amazon.com Inc. AMZN and Microsoft Corp. MSFT are intensifying their pursuit of industrial-scale quantum computers, with recent breakthroughs bringing the decades-old dream within reach by 2030.
Quantum Breakthrough Momentum Builds
The race accelerated after IBM published its quantum computer blueprint in June, claiming to have “cracked the code” for full-scale machines. “It doesn’t feel like a dream anymore,” Jay Gambetta, head of IBM’s quantum initiative, told Financial Times. “I really do feel like we’ve cracked the code and we’ll be able to build this machine by the end of the decade.”
Google demonstrated significant progress with error correction capabilities late last year. “All the [remaining] engineering and scientific challenges are surmountable,” said Julian Kelly, head of hardware at Google Quantum AI, according to the FT report.
Scaling Challenges Remain Formidable
Current systems operate with fewer than 200 qubits—quantum computing’s basic building blocks. Industrial applications require scaling to 1 million qubits or more. Amazon’s Oskar Painter warned the engineering effort remains substantial, predicting useful quantum computers are “still 15-30 years away.”

Error Correction Race Heats Up
Google leads in error correction demonstrations, using surface code technology requiring 1 million qubits for practical calculations. The company targets $1 billion in system costs through 10x component cost reductions.
IBM pivoted to low-density parity-check codes, claiming 90% fewer qubits needed than Google’s approach. However, this requires longer qubit connections—a technical challenge IBM claims to have recently solved.
Market Impact Accelerates
Nvidia Corp. NVDA CEO Jensen Huang‘s June comments about quantum computing reaching “an inflection point” sparked rallies in quantum stocks, including Quantum Computing Inc. QUBT and Rigetti Computing Inc. RGTI. IonQ Inc. IONQ raised $1 billion in July, targeting 2 million physical qubits by 2030.
The Pentagon’s DARPA launched studies identifying fastest-scaling quantum technologies, while concerns mount over quantum computers potentially cracking Bitcoin BTC/USD encryption 20 times faster than previously estimated.
