Turns out quantum is more feelings than formulas..!
A few days back, I’ve set foot on one more tiny trip in Quantum with @IQM and I felt like someone opening a window in a room I didn’t even know was locked 🔏. I’ve been curious about quantum computing lately.. hearing fancy words like “qubits”, “entanglement”, and trying to understand Quantum a little more than I actually did 😅
Today is one of such days I’d say.. I didn’t learn quantum concepts…
I kind of felt them 😌. Not fully, not deeply, just enough to sense that there’s a different logic underneath reality if you’re willing to listen.
🧠 Qubits aren’t 0 or 1… they’re a silent “maybe”
The simplest idea we touched today was this:
A qubit is not 0 or 1 until we ask it to choose.
Until then,
it’s gently suspended somewhere between those possibilities.. like a candle flame 🕯️that can’t decide which direction to flicker.
Then came ∣+⟩.. That’s like a tiny glow✨that refuses to pick a side.
Made my not the first, but the first using qrisp today..👇🏻
from qrisp import QuantumVariable
q = QuantumVariable(1)
q.H() # Hadamard
result = q.measure()This single H() gate turns ∣0⟩ into a perfect superposition.
In a simulator, it behaved exactly like a coin flip. On hardware, imperfectly but honestly and somehow that imperfection made the whole thing feel more real.
🔗Entanglement- spooky ☠️ but also strangely poetic 💞
Built something called a Bell state.
Two qubits that don’t just correlate.. they belong to the same story. One changes, the other instantly responds, even if you separate them. Not because one tells the other what to do, but because they were written into the same sentence when the universe wasn’t paying attention.
q1 = QuantumVariable(1)
q2 = QuantumVariable(1)
q1.H()
q2.CNOT(q1)
q1.measure()
q2.measure()One flip affects both, even though individually they look random.

I swear physics feels like poetry when you stop forcing yourself to sound smart !
Gates suddenly 🔁 personalities
Instead of memorizing symbols, Picture gates like actions:
- X flips reality.
- H invites uncertainty.
- Z changes something invisible.
- Y flips + twists.
- S and T rotate the qubit’s “direction” a little.
- Measurement collapses possibilities.
Gates are choices more than just mathematical tools..!
Measuring isn’t observing.. it’s forcing a decision
The simulator patiently tells you probabilities: “60% zero, 40% one…” But measurement says: “No more maybe. Tell me what you are right now.” And the qubit snaps into one definite answer.
That tiny snap is strangely dramatic.😅
🌐GHZ states — “all in or nothing at all”
If a Bell pair is two people agreeing, GHZ is an entire group taking a collective oath.
Either everyone is 0 or everyone is 1
qs = QuantumVariable(10)
qs.H(0)
for i in range(1,10):
qs.CNOT(i-1, i)Here is a tiny code sketch 👆🏻. On the simulator, it’s beautiful but on the real hardware, noise creeps in fast as qubits increased.
It’s dramatic, fragile, beautiful, and apparently very sensitive to noise. And when noise becomes too much to handle, the “promise” breaks and reality collapses into randomness.
Somehow that feels very… human.!!🤞🏻
🌱 So to wrap upp..
“Even uncertainty is a valid state of existence. You don’t need to collapse into one answer before your time.”
In a world that constan🥹tly asks us to declare our plans, lock our decisions, and know our future 🤯, I found strange comfort in a qubit’s hesitation..
That’s probably the first “quantum rule” I want to remember.. not just the math, but the mindset..!! 💯
