CS and AI students at MIT, Stanford, CMU, Berkeley, IITs, Tsinghua and ETH are hired on depth beyond tool use: model internals, systems and hardware. Passing earns a founder-signed Science of Apps certificate with a credential ID and QR code that recruiters can verify.

Can quantum computers break today's encryption?

A large, fault-tolerant quantum computer running Shor's algorithm could break RSA and elliptic-curve cryptography, which is why NIST published post-quantum standards such as ML-KEM (FIPS 203) in 2024; today's noisy machines cannot yet do this.

What is a logical qubit?

A logical qubit is an error-protected qubit encoded across many physical qubits using an error-correcting code such as the surface code, so that errors can be detected and corrected faster than they accumulate.

Can I take the Quantum Computing Fundamentals Certification from any country?

Yes. The test is online, in English and free everywhere — people take it from India, the US, the UK, Europe, Africa, Latin America and Asia-Pacific. Your certificate is dated with your own local date and can be verified from anywhere at scienceofapps.com/certification/verify/.

How long is the Quantum Computing Fundamentals Certification?

20 questions — 5 from each of 4 skill areas — with a 20-minute limit. You need 70% (14 of 20) to pass and 90% for distinction.

How hard is the Quantum Computing Fundamentals Certification?

Nothing. There is no fee to take a test, to receive the certificate, to have it emailed or to verify it, and no sign-up.

How are the tests graded?

On our server, not in your browser. The answers never reach the page until you submit, so a certificate can only be earned by passing. Each certificate gets a unique credential ID stored by Science of Apps.

What happens if I don't pass?

You see your score for each area and every question with the correct answer and why, with the published source behind it. You can retake after 30 minutes, and the retake draws questions you haven't seen yet.

Do the certificates expire?

No. Every certificate is dated, so it always shows when you passed. Retake a test any time for a newer date or a higher score.

Can I add the certificate to LinkedIn?

Yes. After you pass, Add to LinkedIn opens the Licenses & certifications form with the certificate name, Science of Apps as the issuer, the issue date, your credential ID and the verification link filled in. You can also download it as a PDF or PNG, and it's emailed to you as a PDF.

How can an employer verify my certificate?

Every certificate has a credential ID and a QR code. Scanning it, or entering the ID at scienceofapps.com/certification/verify/, shows the holder's name, the certification, the score and the issue date from our records.

Are these accredited qualifications?

No. They are Science of Apps' own assessments of applied skill. They aren't issued by a university or standards body, and they work best alongside a portfolio that shows the skills in real work.
