Each card is drawn from quantum vacuum fluctuations measured in real time by the Australian National University. Not an algorithm pretending to be random: an actual measurement of the void.

Ordinary software randomness is not random. A pseudo-random number generator (PRNG) is a deterministic algorithm: give it the same seed and it produces exactly the same sequence forever. The shuffle looks chaotic, but every "random" card was fixed the instant the seed was chosen.
A quantum reading replaces that algorithm with a physical measurement. In quantum mechanics the outcome of measuring a system in superposition is, as far as any experiment can tell, fundamentally undetermined until the measurement happens. The wavefunction "collapses" to one value, and no hidden variable, seed or prior state predicts which. The number that selects your card did not exist, anywhere, until the moment the vacuum was measured.
Practically that means: nobody can reproduce your spread, no algorithm chose it, and the sequence that selected your cards is as close to true non-determinism as physics allows. When the quantum stream is unreachable, this page says so and uses your device's cryptographic hardware entropy instead, which is unpredictable but not quantum.
The Australian National University's Quantum Random Numbers service, run by the Department of Quantum Science in Canberra, generates random numbers by measuring the quantum vacuum. Even a perfect vacuum is not empty: the electromagnetic field has irreducible zero-point fluctuations, often described as virtual particles spontaneously appearing and vanishing.
A laser beam is split, and a balanced detector measures the tiny differences in the vacuum field's amplitude between the two arms. Those differences are amplified, digitised and whitened into a high-speed stream of bits (gigabits per second) and published through the ANU Quantum Random Numbers API.
This page requests bytes from that API (through a same-origin relay that holds the official key, so no key is exposed in your browser). Each byte is a fresh measurement of the vacuum, mapped onto the 78-card deck without replacement, so every card in a spread is unique.
Tarot began in northern Italy in the early 15th century as carte da trionfi, "triumph cards": a luxurious card game played at the courts of Milan, Ferrara and Bologna. The hand-painted Visconti-Sforza decks (around 1450) are among the oldest surviving. The 22 allegorical trump cards, which we now call the Major Arcana, were added to a regular four-suit deck to create the game of tarocchi.
For three centuries the cards were simply a game. The occult interpretation arrived in 1781, when Antoine Court de Gébelin claimed the trumps encoded ancient Egyptian wisdom. The fortune-teller Etteilla published the first deck designed for divination a few years later, and 19th-century French occultists such as Éliphas Lévi linked the cards to Kabbalah and astrology.
The modern visual language comes from the Rider-Waite-Smith deck of 1909, illustrated by Pamela Colman Smith under Arthur Edward Waite, which gave fully illustrated scenes to all 56 Minor Arcana. Today Tarot is widely used as a tool for reflection: the archetypal images, as Carl Jung noted, act as prompts that help us notice what we already sense. The cards do not predict; they ask better questions.
