IBM is set to build the largest quantum computer to date by interconnecting smaller machines to form a single system with a record-breaking number of quantum bits, or qubits. The company aims to take the first steps toward this goal in 2025, setting a new qubit record, and ultimately plans to more than triple the size of the current largest quantum computer.
Just six years ago, IBM introduced its first commercial quantum computer, featuring 20 qubits and accessible to researchers via the internet. Today, the company’s most advanced quantum chip, known as Condor, boasts 1,121 qubits. However, according to IBM’s Jay Gambetta, most users of the company’s quantum computing services typically work with just 100 qubits.
The Journey to Mega-Qubits
Just six years ago, IBM introduced its first commercial quantum computer, featuring a modest 20 qubits. This pioneering effort made quantum computing accessible to researchers worldwide through the internet, marking a significant milestone in the field. Fast forward to today, and IBM’s most advanced quantum chip, the Condor, boasts an impressive 1,121 qubits. This represents a remarkable leap in quantum technology, showcasing the rapid advancements in the field.
However, despite the Condor’s capabilities, IBM’s Jay Gambetta notes that most users of their quantum computing services typically work with around 100 qubits. This highlights the practical challenges of harnessing the full potential of large quantum computers.
Key Milestones and Future Plans
- 2025: Stepping Stone to Mega-Qubits: IBM plans to take the first significant steps toward its mega-qubit goal in 2025. This phase will focus on developing and implementing the necessary technologies to interconnect smaller quantum computers effectively.
- Record-Breaking Qubits: The 2025 milestone is expected to set a new record for the number of interconnected qubits, demonstrating the feasibility of this ambitious project.
- Tripling Current Capacity: IBM’s ultimate goal is to more than triple the size of its current largest quantum computer. This will create a system with an unprecedented number of qubits, unlocking new possibilities for quantum computing.
The Significance of Interconnected Quantum Computers
Interconnecting quantum computers is not simply a matter of scaling up existing technology. It requires overcoming significant technical hurdles, including:
- Maintaining Qubit Coherence: Qubits are notoriously fragile and susceptible to noise and interference. Interconnecting them without losing coherence is a major challenge.
- Developing Efficient Interconnects: The connections between quantum computers must be fast and reliable to ensure efficient communication and computation.
- Software and Algorithms: New software and algorithms are needed to effectively utilize the power of interconnected quantum computers.
