Description: Clever science pun design

Description: Typeset in LaTeX, not AI-generated. Minimal on purpose. The eigenstate that makes quantum phase estimation work, the piece of Shor's algorithm that lets a quantum computer find a period a classical computer would need exponential time to find.

Description: A framed rose and bird surround circular New Direction lettering in black and white with a reflective feel.

Description: Typeset in LaTeX, not AI-generated. Minimal on purpose. The bosonic error-correcting code that encodes a qubit into the continuous states of a single oscillator, a key building block for photonic quantum computers.

Description: Typeset in LaTeX, not AI-generated. Minimal on purpose. The maximally entangled two-qubit states that make quantum teleportation, superdense coding, and tests of quantum nonlocality possible.

Description: Typeset in LaTeX, not AI-generated. Minimal on purpose. The equation that governs how a quantum system evolves over time, the foundation of quantum mechanics, relating a particle's wavefunction to its energy.

Description: Typeset in LaTeX, not AI-generated. Minimal on purpose. The rule that turns observed evidence into updated belief, the foundation of Bayesian inference, used everywhere from spam filters to medical diagnosis.

Description: An amaryllis flower illustrated in expressive black ink brushstrokes with a clean minimalist composition. Bold strokes, layered ink variation, and visible brush texture define the broad petals, central stamens, and sturdy stem, creating a recognizable botanical form while maintaining a modern monochrome style. The flower emerges through gesture and contrast rather than detailed realism. Graphic and understated, this botanical illustration is ideal for fans of minimalist nature art and contemporary ink design. A refined piece suited for apparel and accessories.

Description: Typeset in LaTeX, not AI-generated. Minimal on purpose. The principle that sets a fundamental limit on how precisely position and momentum can be known at the same time, one of the defining ideas of quantum mechanics.

Description: Typeset in LaTeX, not AI-generated. Minimal on purpose. The operator at the heart of Grover's algorithm, the quantum search that finds an item in an unsorted list quadratically faster than any classical method.

Description: Typeset in LaTeX, not AI-generated. Minimal on purpose. The four equations that unify electricity, magnetism, and light into a single theory: Gauss's law, no magnetic monopoles, Faraday's law, and Ampère's law with Maxwell's correction.

Description: Typeset in LaTeX, not AI-generated. Minimal on purpose. The transform that powers Shor's algorithm and much of quantum computing: it turns a basis state into an equal superposition weighted by roots of unity.
