"What are the latest developments in quantum computing?"

Sonar Pro

Researchers at IBM unveiled a 1,000-qubit processor in late 2024, marking a major milestone in fault-tolerant quantum computing. Google's Willow chip demonstrated quantum error correction below threshold for the first time [1].

Microsoft announced a topological qubit breakthrough in early 2025, claiming 99.9% fidelity — a key requirement for practical quantum advantage in cryptography and drug discovery [2][3].

How it works

Perplexity Sonar Pro in three steps.

1

Ask your question

Type any question — news, research, market data, technical topics. No need to phrase it differently from how you'd ask a colleague.

2

Sonar Pro searches the web

The model queries live sources in real time, reads the most relevant pages, and synthesizes a coherent answer — not a list of links.

3

Cited answer, instantly

You get a clear answer with numbered citations. Cross-reference with what ChatGPT or Claude say — in the same thread.

What makes Sonar Pro different

Standard LLMs hallucinate and go stale. Sonar Pro is built differently.

Standard LLMs

  • Training cutoff — can't answer about recent events
  • No sources — you can't verify where facts came from
  • Confidently wrong on fast-moving topics
  • Requires you to search separately and cross-reference manually

Perplexity Sonar Pro

  • Live web search on every query — always current
  • Inline citations for every factual claim
  • Synthesized answer — not just a list of search results
  • Deep research mode for multi-step complex queries

What people use it for

Sonar Pro excels wherever freshness and accuracy matter most.

Market & competitor research

Get current pricing, product launches, and funding rounds — with the source links to share with your team.

Breaking news & current events

Ask about anything that happened in the last hour. Sonar Pro has no cutoff date — it searches now.

Scientific & academic research

Find recent studies, papers and publications. Each citation links directly to the source — no hallucinated references.

Better together — the MultipleChat advantage

Sonar Pro is most powerful when it runs alongside the other models.

Cross-check answers

Ask the same question to Sonar Pro and ChatGPT-5. See where they agree — and where Sonar's live sources contradict the model's training data.

Research then reason

Use Sonar Pro to gather current facts, then hand off to Claude or Gemini for deeper reasoning, writing, or analysis of what you found.

Spot disagreements

MultipleChat's Sources & Disagreements feature highlights when models contradict each other — so you know exactly what to verify.
