Store description excerpt
Superposition. Entanglement. Interference. Everyone describes them. Schrödy Lab lets you watch them happen. Build a quantum circuit with your finger, run it, and see the exact state of every qubit - not a rough sample, the real thing. It runs entirely on your iPhone, offline, with no account and no queue. WHY IT'S DIFFERENT Most quantum tools hand you measurement counts and leave you to infer what happened. Schrödy Lab computes the full state vector, so you see the probability AND the phase of every basis state. Phase is where quantum computing actually lives. It is what makes interference possible, what Grover's algorithm manipulates to find an answer - and it is exactly what sampling throws away. Here you can see it, on every state, at every step. SEE THE ALGORITHM THINK Step through a circuit one column at a time. Watch a uniform superposition form, watch the oracle flip a phase you would otherwise never notice, and watch the diffusion step turn that invisible change into a visible answer. This is the moment quantum computing stops being abstract, and most people never get to see it. FROM YOUR POCKET TO A REAL NOTEBOOK Every circuit you build is translated, live, into runnable Python - for Cirq and for Qiskit, each following its own qubit-ordering convention. Imports, registers, the full gate sequence and the simulation call, ready to paste and run. Sketch an idea on the train, run it on a real backend when you get home. THE FULL TOOLKIT Hadamard, Pauli-X, Pauli-Y, Pauli-Z, phase S and T, the parametric rotations RX, RY and RZ with any angle you type, CNOT, controlled-Z, Toffoli and measurement. Set any qubit's initial state to |0> or |1>. Build up to 8 qubits - all 256 amplitudes, computed exactly. CLASSIC ALGORITHMS, READY TO RUN Load the Bell state, GHZ, uniform superposition, or Grover's search for 2 and 3 qubits with one tap. Take them apart gate by gate and see why they work. FOR STUDENTS, TEACHERS, AND THE CURIOUS If you are learning quantum computing, this is the intuition that textbooks cannot print. If you teach it, it is a demo that fits in your pocket and needs no projector, no install and no Wi-Fi. If you already work in the field, it is a scratchpad for trying a circuit before you open a laptop. HONEST ABOUT WHAT IT IS This is an exact, idealised simulator. It does not model decoherence, gate error or readout noise, and it does not run on physical qubits. That is the point: with no noise in the way, the mathematics is visible. It is a tool for learning, teaching and prototyping - not a substitute for real hardware. FREE Circuits of up to 2 qubits, with the full simulator, step-by-step mode, and Cirq and Qiskit export. Enough for superposition, the Bell state, entanglement and interference - the whole introductory arc, at no cost, forever. SCHRÖDY LAB PRO Up to 8 qubits. Save and reopen your circuits. Every preset and every gate, including Toffoli, GHZ and Grover's search. USD 4.99 per year, with a 7-day free
