Microsoft’s warning that the quantum-security clock is moving faster has put a beaten-down quantum stock back on Wall Street’s radar.
Quantum Computing Inc. (NASDAQ: QUBT) was trading around $8.75 on Thursday, while an average analyst price target on the stock is $18.33, implying roughly 111% upside current levels.
The setup is compelling, but risky, as QUBT is a speculative quantum and security trade, not a proven winner.
Microsoft’s quantum warning changes the security clock
The latest catalyst is not coming from Quantum Computing itself, but from Microsoft.
Microsoft said it is accelerating its Quantum Safe Program and now aims to transition products and services to post-quantum cryptography by 2029.
Azure CTO Mark Russinovich wrote that advances in quantum research have “shifted the risk horizon” and that cryptographically relevant quantum computers could arrive sooner than previously expected.
In simple words, the risk is not that quantum computers are breaking encryption today, but attackers can steal encrypted data now and decrypt it later, once quantum machines become powerful enough.
Microsoft called this the “harvest now, decrypt later” problem and said organisations are already prioritising long-lived sensitive data for protection.
The company’s transition plan focuses on practical plumbing with TLS 1.3, crypto-agility, certificate trust chains, code signing, hardware-backed protections and data protection.
That matters for investors because it suggests quantum-safe security is moving from research debate to enterprise budget item.
Why QUBT is being linked to the quantum-security trade
Quantum Computing Inc. is being watched because it is not pitching itself only as a quantum-computing hardware story.
The portfolio spans integrated photonics, quantum optics, cybersecurity, sensing and secure communications.
Its March 2026 acquisition of NuCrypt added quantum communications technology, in a deal valued at $5 million.
NuCrypt brought systems, products and patents tied to quantum optics, RF-photonics and photonic signal processing.
QUBT then added more manufacturing depth in June by completing its acquisition of NHanced Semiconductors.
The company said the deal provides a foundation for scalable chip manufacturing of its quantum and photonics technologies, supporting commercialisation and a vertically integrated platform spanning research, development and manufacturing.
That is why the Microsoft warning matters. If enterprises, governments and cloud providers start spending more aggressively on post-quantum security, investors may look for smaller pure-play companies with exposure to quantum photonics, secure communications and related infrastructure.
Rosenblatt analyst John McPeake has made that bull case directly.
He said QCi has “legitimate quantum assets across photonics, compute, security, and sensing,” along with thin-film lithium niobate fabrication capabilities that could support integrated quantum photonics, nonlinear optics and optical waveguides.
Analysts see upside, but the stock remains speculative
The analyst math is where the projected upside comes from.
Benzinga lists a $18.33 consensus price target for QUBT, with a $30 high target from Ascendiant Capital and a $10 low target from Cantor Fitzgerald.
From a stock price near $8.75, that average target points to roughly 111% upside, while the Street-high target implies far more.
Ascendiant Capital’s Edward Woo has been among the more bullish analysts. He reiterated a Buy rating and raised his target to $30 from $27.
Woo said Wall Street’s revenue expectations for QUBT appear achievable, based partly on management conversations and the company’s acquisition-led revenue growth.
Lake Street also remains constructive as the firm reiterated a Buy rating and $16 target after the NHanced acquisition, saying the deal accelerates QUBT’s shift from research and prototyping toward scalable commercial production.
At the same time, the firm noted that the financial contribution from the deal has not yet been quantified, which is an important caveat.
