At Classiq, we believe that efficient coding of quantum circuits is key to maximizing the value of current and future quantum computers. That’s why we are launching a quantum coding competition with total prizes of $25,000 to reward those that can create the most efficient circuits. The top winners will also be profiled in The Quantum Insider.

Below are four quantum computing problems. You are welcome to submit answers to as many or as few as you want. Submissions are judged according to the circuit depth or the number of two-qubit gates that they use, and your goal is to minimize this number. Any person 16 or older worldwide is welcome to submit, except Classiq employees, their families, and the judges.

The official rules are here.

each problem

These prizes are for **each** problem separately

$3,000

for the best Solution

$1,500

for the second-best solution

$500

for the third-best solution

youth

For contestant under the

age of 18

age of 18

$1,000

for **each** of the two selected winners

innovative solution

For the most original solutions

$1,000

for **each** of the three most innovative solutions

Winners can choose the cash prize, or choose to have Classiq donate the prize money in their name to one of four charities (**Girls Who Code**, **Code.org**, **National Math and Science Initiative**, **Animal Legal Defense Fund**) as listed in the official rules.

Each problem is judged separately.

You can win prizes for multiple problems, but for each problem, you can only win one prize.

We are presenting four problems, related to optimization, chemistry, finance and gate decomposition. Click on each one for a full description and to submit a solution.

The submission form is at the bottom of each problem. For each solution, you will submit the QASM circuit, the code used to generate it, circuit depth or 2-qubit gate count, and a description of your approach. You may submit multiple solutions per problem.

All solutions must be submitted by 11:59 PM US Eastern time on June 5th. *Submissions are closed.*

See ResultsSubmit a solutionSource Code

A QASM circuit together with the source code used to generate it. Use any platform you wish - Q#, Qiskit, PennyLane, etc. - but not the **Classiq quantum algorithm design platform** - it wouldn’t be fair!

DEPTH and gate count

The overall circuit depth and the number of 2-qubit gates that you used.

description

A description of your approach to help us understand your thought process as well as any other details you can share.

We look forward to reviewing your solution. Here are some things to know:

You are welcome to submit multiple solutions. If you submit something today, and find an improvement later on, you're welcome to submit the new solution as well.

Each problem requires slightly different information. Please make sure you carefully review the problem instructions.

The description of the approach is very helpful to the judges in understanding your work. Please include as much detail as you wish. We're interested in how you approached this problem, how your solution works, how long it took you to develop it, and whether there were particular problems that you overcame. We'd love to hear as much as you want to tell us. You can submit this in the 'description' field or include it as the 'Additional file (optional)' attachment.

The QASM code is how we can verify the 2-qubit gate count and/or circuit depth. It should include only CX and single-qubit unitary gates. **This note** on our Discourse support site might help.

If you created the circuit in something other than QASM, please submit the source code as well.

You will receive an email confirming the submission within a few minutes.
