A quiet period might come as a blessing for quantum-computing stocks. After a tumble last week when chip maker Nvidia's 'Quantum Day' underwhelmed the market, shares of quantum companies were gaining early on Monday.

D-Wave Quantum, IonQ, Rigetti Computing, and Quantum Computing were all rising by between around 3%-5% in premarket trading.

All the companies are involved in quantum computing, the catch-all term for using properties of subatomic particles to work more quickly than is possible with traditional machines, although they have different approaches.

Nvidia on Thursday hosted a roundtable discussion on quantum computing at its GTC conference, where CEO Jensen Huang looked to soften his previous comments that "useful" quantum computers were decades away.

However, the event might have done more harm than good for the sector as Huang noted he was surprised that there were public companies in the sector -- underlining the fact that smaller companies developing the technology are unlikely to generate significant revenue for years to come -- and suggested quantum computers might be better thought of as scientific instruments than a replacement for mainstream computers.

For now, bulls on quantum stocks might prefer a period of silence to let excitement rebuild around the technology.
