Useful quantum computers are fake.

Fault-tolerant quantum computers are fake.

Quantum computers with 10000 times less errors are fake news. ← They used only classical computer's simulation, No quantum computers.

(Fig.1) Overhyped fake news wrongly treats ordinary classical computer's simulation as (fictional) quantum computers with less errors.

Fake quantum computer with 10000 × lower errors.

Alice & Bob company used only ordinary classical computer's simulation, so their quantum computer's reducing errors to 1/10000 is fake.

Overhyped fake news (2026) wrongly claims
"Alice & Bob has achieved a breakthrough in quantum error correction, slashing the logical error rate by a factor of 10,000"

"These error rates will (= still unrealized ) make it possible to feasibly tackle problems like complex molecular simulation sooner than expected"

Just classical (= No quantum ) computer simulation

↑ Another news on the same subject says ↓

2nd-paragraph says -- Imaginary future quantum computer
"These new Elevator Codes would give Alice & Bob the option to make future (= still unrealized ) quantum processors dramatically more accurate.... the researchers expect (= still unrealized ) to be able to reach a 10,000 times lower logical error rate"

5th-paragraph says -- Just classical computer simulation
"Also, this study is based on what our classical computers can simulate"

↑ So this latest overhyped Alice & Bob's quantum computer reducing errors was fake, which was just a classical (= Not quantum ) computer simulation ( this-11th-paragraph, this-5~6th-paragraphs ).

↑ This latest Alice & Bob's paper's p.4-right says
"Results of numerical simulations" ← this numerical simulation means just a classical computer's simulation of some quantum methods without using quantum computers.

Alice & Bob has No real quantum computers.

Alice & Bob made just one error-prone qubit (= taking only 0 or 1 value ), far from millions of qubits required for an useful fault-tolerant quantum computer.

In fact, This Alice & Bob company has made only one useless qubit (= one qubit takes only 0 or 1 value, so still Not a quantum computer )

This-Paving he way to fault-tolerant quantum computers-3rd-paragraph (2025) says
"Of course, there are still challenges ahead... Thus far, the record pertains to a single qubit staying in one piece. The company (= Alice & Bob ) plans (= still unrealized ) to test two-qubit gates (like entangling operations) on the Helium chip next. Two-qubit operations might introduce new avenues for errors"

↑ So Alice & Bob made only one qubit (= 0 or 1 bit ), still did Not make even two qubits.

↑ Just one useless qubit is far from a practical quantum computer needing millions of qubits ( this-last-paragraph ) which are impossible to realize forever..

Alice & Bob's cat qubit is too error-prone, useless

Alice & Bob made only one useless qubit whose error rate is far higher (= 6% ) than the practically-required error rate of less than 10^-15.

Even this single (cat) qubit's error rate of Alice & Bob is too bad with fidelity 94% (= one qubit-operation error rate is 6% or 0.06, which is far worse than a practical classical computer's error rate less than 10^-20 ).

This or this site (2025) ↓

2nd-paragraph says -- Too high error rate
"The experiment also demonstrated a Z gate (= just one single qubit 0 or 1 operation ) with a 94.2% fidelity (= one qubit's error rate is 6%, which is too high, impractical )"

4th-paragraph says -- Just one useless qubit
"The next step for the company will be to evaluate the performance of this result under a two-qubit gate (CNOT)." ← Still two-qubit gate operation has Not been realized ( this-2~3rd-paragraph ).

As a result, "Fault-tolerant quantum computers correcting errors !" is overhyped fake news.

Quantum computing for AI drones is fake.

Just 5 qubits (= one qubit takes only 0 or 1 value ) are useless for defense AI drones.

(Fig.2) Overhyped quantum computers are useless for any technologies.

Just 5 qubits are useless for drones.

Zenatech's just 5 qubits (= one qubit takes only 0 or 1 value ) is useless for military drones, far from millions of qubits required for a practical quantum computer.

The 1st-paragraph of this overhyped news (2026) says
"The company currently expects to have the five qubit quantum prototype complete and be operational later in 2026.... the company’s ZenaDrone drones and drone swarms, providing real-time actionable insights and decision-support for military and government applications."

↑ Just 5 qubits (= just 5 useless bitstring 00101, one qubit takes only 0 or 1 value, so still Not a quantum computer ) are completely useless for any technologies such as AI drones.

Far from practical millions of qubits.

↑ These 5 qubits are far from millions of qubits required for a practical quantum computer which is impossible to realize forever.

↑ This-Today's quantum technology (2025) says -- Far from million qubits
"Despite the headlines, we do Not yet have a fully scalable, fault-tolerant quantum computer. That would require millions of stable quantum bits ( qubits). Currently, the leading platforms operate in the hundreds or low thousands, with significant error rates"

This-lower-Potential negatives say -- 5 useless qubits
"The company is still in the early stages of developing a proprietary quantum computer hardware platform,.. There is No mention of established partnerships or contracts with government entities.."

As a result, quantum computers are useless forever, which need overhyped fake news to deceive ordinary people.
