Investing.com -- Rosenblatt Securities started coverage on quantum computing companies, with Buy rating Rigetti Computing Inc (NASDAQ:RGTI) and Quantum Computing Inc (NASDAQ:QUBT) on long-term growth.
Rosenblatt initiated Rigetti at Buy with a $40 price target on modular approach to scaling superconducting qubits and its vertically integrated internal fabrication capability.
Rigetti has delayed the launch of its 108-qubit Cepheus system after missing its two-qubit gate fidelity target of 99.5%, instead reporting 99.0%. Management has said it expects to resolve the issue by the end of the first quarter.
Rosenblatt flagged this as a competitive gap.
Superconducting peers such as IBM and IQM have already reported two-qubit fidelities above 99.8%, while D-Wave Quantum could potentially achieve even lower error rates following its acquisition of Quantum Circuits.
Rigetti’s installed base of 18 quantum machines, its in-house QPU fab, and its multi-chip architecture using tunable couplers give it a credible path to scale.
Rigetti’s collaboration with Riverlane on quantum error correction is also a medium- to long-term positive.
The stock is valued at about 76 times earnings, which Rosenblatt analysts say is justified by expected earnings growth of over 90%, implying a PEG ratio below one.
Quantum Computing Inc: cash, fabs and nearer-term revenues
Quantum Computing Inc. at Buy was given a $22 price target, calling the company as a diversified quantum and photonics play rather than a pure gate-based quantum computing bet.
QCi has cash balance of $1.6 billion and zero debt and interest income currently exceeds operating expenses.
While revenues remain minimal, at $1.2 million this year, Rosenblatt expects a step-change once the company completes its acquisition of Luminar’s LSI fabs, which could add roughly $25 million in annual revenue.
A central part of the bull case is QCi’s thin-film lithium niobate (TFLN) fabrication strategy. The first fab is already operational and aimed at internal needs and low-volume customers, while a second, higher-volume fab could dramatically expand capacity and revenue if fully built out.
Rosenblatt values QCi at roughly 10 times long-term revenue potential, discounting projected 2035 earnings at an aggressive 25% rate to reflect early-stage risk.
