Quantum algorithms save time in the calculation of electron dynamics
Quantum computers promise significantly shorter computing times for complex problems. But there are still only a few quantum computers worldwide with a limited number of so-called qubits. However, quantum computer algorithms can already run on conventional servers that simulate a quantum computer. A team has succeeded in calculating the electron orbitals and their dynamic development […] more…
Microlaser chip adds new dimensions to quantum communication
With only two levels of superposition, the qubits used in today’s quantum communication technologies have limited storage space and low tolerance for interference. Engineering’s hyperdimensional microlaser generates ‘qudits,’ photons with four simultaneous levels of information. The increase in dimension makes for robust quantum communication technology better suited for real-world applications. more…

Thinking like a cyber-attacker to protect user data
Researchers have shown that a component of modern computer processors that enables different areas of the chip to communicate with each other is susceptible to a side-channel attack. An attacker can monitor how traffic from two different cores on a processor interferes with each other to extract secret information, like a cryptographic key. more…
A key role for quantum entanglement
A method known as quantum key distribution has long held the promise of communication security unattainable in conventional cryptography. An international team of scientists has now demonstrated experimentally, for the first time, an approach to quantum key distribution that is based on high-quality quantum entanglement — offering much broader security guarantees than previous schemes. more…
Quantum cryptography: Hacking is futile
An international team has successfully implemented an advanced form of quantum cryptography for the first time. Moreover, encryption is independent of the quantum device used and therefore even more secure against hacking attempts. more…
Quantum digits unlock more computational power with fewer quantum particles
For decades computers have been synonymous with binary information — zeros and ones. Now a team has realized a quantum computer that breaks out of this paradigm and unlocks additional computational resources, hidden in almost all of today’s quantum devices. more…
‘Pulling back the curtain’ to reveal a molecular key to The Wizard of Oz
Many people and companies worry about sensitive data getting hacked, so encrypting files with digital keys has become more commonplace. Now, researchers have developed a durable molecular encryption key from sequence-defined polymers that are built and deconstructed in a sequential way. They hid their molecular key in the ink of a letter, which was mailed […] more…
