Shares of IonQ Inc., D-Wave Quantum Inc., and Rigetti Computing declined around 4% on Tuesday. This movement followed a decision by an analyst at Mizuho Securities to reduce the price targets for all three quantum computing companies.

Analyst Vijay Rakesh lowered the price target for IonQ Inc. from $80 to $61. For D-Wave Quantum Inc., the target was cut from $40 to $31, and for Rigetti Computing, it was reduced from $43 to $33. The report indicated that Rakesh maintained an "Outperform" rating on all three stocks.

The analyst remains optimistic about the sector's long-term prospects. The report noted his mention of the increasingly widespread application of NVQLink technology, which could enhance quantum error correction and enable systems to integrate quantum and classical computing.

Global investment in the field also appears to be growing. The United Kingdom is projected to invest approximately $2.7 billion in quantum computing over the next four years, while Canada may allocate about $1 billion for defense-related projects. Rigetti Computing also plans to invest around $100 million in the UK.

The analyst suggested that while the industry might face near-term pressure, it retains long-term upside potential, supported by technological advancements and increased funding.
